Advice on life??

So. I have a lot of problems. For one I'm not out. Due to fear of losing my friends. (Notice how I said only friends). Second I have melancholy. Due to horrible parents and horrible brothers (3), and the mentioned still in the closet situation. Finally, I was recently with a great guy; I ended it. I regret that so much and I feel stupid. I feel like the weight of the world is on my shoulders and I'm ready to just let it all crush me at once. (I'm not above giving more description on the topics. I just want to know someone will listen)
