I second DirectoRik's suggestion that "you could expand your network of contacts by connecting here on indietalk." I recommended to another newbie making many of your same mistakes that they check out the many helpful crowdfunding articles at "Seed & Spark". Your approach is singled out as one to avoid: You joined this forum just to ask for money; you don't care about the forum or anyone in it, only what you can extract from us. That is bound to stir more resentment than support. Picture it this way: A bunch of friends are having a party, then you show up; nobody knows you or anything about you and nobody invited you, but you ask everyone to give you money. Why the hell should we? Who the fuck are you?
The most successful tactic generally is to 1) Identify your audience. Who is your movie for? The answer is never, "Everyone!" There has never been and never will be a movie that appeals to everyone. Who is your movie for? If you can't answer that question, you're not ready to make the movie. 2) Figure out where your audience congregates. Are you making a horror movie? Then join horror-movie-fan forums and Facebook Groups. 3) Don't ask for money right away! Become a member of the community. Post about the horror movies you've enjoyed, and why you enjoyed them. Watch other people's movies and comment on them. It's not an overnight process, but it is quite swift. Once you are known as a good guy in the community, we will gladly donate to your crowdfunding campaign -- to help out our friend.
That leads me to another oft-repeated (and oft-ignored) fact: Most crowdfunding donations do not come from strangers. They come from your extended network: the people you know, and the people they know. (That number of people times your likely response rate times the average donation gives you the budget of your movie.) Get your cast and crew to promote your crowdfunding campaign to their contacts. (And don't resent them if they don't. What you are doing is asking them to ask their friends to give you (a stranger) some of their money. Not everyone is comfortable asking their friends that. Remember who's doing whom a favour here: funding and selling the movie is your job, not theirs.)
You failed to achieve the goal you set in your last campaign. Now you have a new campaign, where you are asking for more than twice that amount of money. What has changed that you think you can go from not being able to raise five grand to being able to raise ten grand? Apparently nothing, because your new campaign is failing worse than your first one: less money and fewer backers. This is entirely to be expected. Everybody who supports you will donate to your first campaign; every subsequent campaign will see that group decrease by about 50 percent. (You're actually doing just a smidge better than average: your second campaign has just over half the backers of your first, although only one-third the bucks.)

On a completely separate topic, I would like to tread gently: I suggest that the content of the movie you want to make may be limiting your audience appeal. I have seen this exact movie over and over again, pushed by creators acting exactly as you are now, for 34 years. From how and what you present, I can already tell what kind of person you are and what movie you will make, and I do not believe that this project is a movie that people will want to see. I can see that it is very important to you to make this movie. Do you have any reasons to think that your movie will be interesting to people who aren't you? What are those reasons? There's your hook!
Making any movie requires a great deal of hard work, and it is very easy to do all that hard work and end up with a bad movie. That said, here are some movies that the world does not need to watch again. We have already seen these eleventy-squillion times:
1) A semi-autobiographical short about you heroically coming out as gay, or heroically overcoming abuse, or heroically dealing with mental illness. Art is therapeutic, not therapy. I'm really sorry that you've had a hard life, and I will advocate and work for public policy that helps people who need it -- but that is a far cry from saying that this will make an interesting movie. You had better have a damned good point other than "This is what I went through," if you want to make a movie people will watch out of something other than politeness. Extra cliche points if you reply to critics in anger, "This actually happened!" So what? It's still a bad movie.
2) A feature-length dramedy about four twenty-something young men who throw a house party and connect or fail to connect with the women in their lives. Extra cliche points if one of them comes out as gay.
3) A dramatic short about two estranged family members who reconnnect at the funeral of a third family member. Extra cliche points if the deceased committed suicide.
4) A noir drama about a jaded hitman who just wants to feel a human connection. Extra cliche points if he spends a lot of time sitting alone smoking a cigarette and staring into the middle distance. Extra, extra cliche points if it's shot in black-and-white.
5) Fan films, especially Batman fan-films. You can't legally show these films to anyone except your own friends whom you invite into into your own living room, but the major IP owners have usually been tolerant as long as you don't charge money for your Amateur Hour. Always remember: you're playing in someone else's sandbox. At any time some low-level lawyer at Warner Discovery can get your fan-film pulled from YouTube, and the law is completely (and rightly) on their side. (Creators behind these projects usually have a multi-movie slate planned that will finally "do Batman right", as soon as someone answers their request for James Gunn's cellphone number.)
All that blithered, I sincerely wish you the best of luck with your project and career!
