First of all, it's good that you're proud of who you are. That's really going to help you through this. Make sure you don't let your environment take that pride away. I'm also bi and in a very similar situation, so I know it's really hard to hide sometimes (and just tough in general). You don't actually have to tell anyone though, it's your choice. If you think telling anyone, particularly family, is going to make people not love you, hate you, or even bully you, it's probably not a good idea. I know that may not be what you want to hear, but telling the wrong people can only make things harder.

As far as what you said about just wanting these feelings to disappear...I know EXACTLY how that feels. I learned the hard way that trying to repress it just makes things worse, and it slowly takes away your pride in yourself because you start to believe it's something that you should always hide. That's actually the situation I'm in right now, so I hope my advice prevents the same thing from happening to you.

The part about wanting to date someone of the same sex but not being able to I also totally understand. That honestly is probably the hardest part for me. How you can make it easier, well....whenever you really want a boyfriend, just let your mind wander/daydream a little. I know it sounds pathetic but it can be comforting to escape reality for a bit.

If you don't mind me asking, how old are you? Depending on your age it may not be long at all until you can get out of the homophobic environment you're in now. I know it may not seem that way, but it's true. Do you have a close friend or relative that isn't homophobic that you could maybe confide in?
Even if there isn't anyone you can talk to IRL, there are other ways you can reach out for support:

Those are the main two that have helped me alot. You can PM me any time you want if you want to talk to someone who understands this.
