Sometimes I look at girls and just feel jealousy rise inside  me. I'm pretty sure that even if im not a girl ill end up cross dressing. I'd like to try more of it but of course I wouldn't be able to leave the house wearing those cloth's because people at school would see me.
Luckily my parents are fine with all of this and im sure i could probably cross dress in the house but with them and my brother and sister around it would just feel so awkward.

It would feel worse because I also have anxiety problems. If i have to leave the house even while going to school i feel as if im going to be sick. I get sweaty, itchy (probably because of the sweat) and i get stomach aches because of it. Ive started medication for that though but im just so paranoid with anyone my age. Im usually fine with all adults but when it comes to people my age im always thinking they are gonna torment me, which is probably because Ive been getting harassed at school for years.
Ive taken the action of reporting it for once and  it did work for a select group of people but that was the end of the year. I had to stop going to school for the last week and a half because of it, even when people were nice to me id always feel so awkward. Ive lost all but two of my "friends" due to figuring out they talk shit about me behind my back thanks to someone who i thought was my friend telling a bunch of people i was gay (when i clearly said bi). The two friends i have i don't get to see to often seeing as one is always working now and one is harder to get a hold of.
Both of them are pretty depressed as well with stuff lately and im scared one is becoming and alcoholic and he might still be bulimic. And the other one just sort of lives unhealthily.  
All the things i used to love doing  have become stale to me now. I used to love playing my bass but now i just find it boring and get mad whenever it doesn't sound right. I'm taking keyboard lessons but i never feel any urge to practice with all this shit going on so i mess up at my lessons. I Don't know what to do to feel happy anymore and i feel like theres nothing i can do seeing as how i live in a small and extremely boring town. id appreciate any advice.

Having gender issues can also be tough. When it switches that frequently, i think it is better to cross dress than to surgically change. i know it can feel awkward with your family around, but they are who acccept you for you, so you should try it at home or to yourself in your room. May i ask what makes you jealous of girls?

As for the anxiety problems, you said that they are centered around people your age. One thing, they do with anxiety is they try to construct a list of things that make you least anxious to most anxious. Then you confront those situations one by one. So first you enter the first one, and when you are able to feel comfortable with that, you move on to the next one, and so on until you begin overcoming your anxiety. That hopefully can be helpful.

im sorry about things not going so well with that group and having to lose two "Friends" because they werent really Friends. i know you do not get to see the two Friends that you have that often, but when you can you should try to spend time with them, it may do you all some good to try and cheer each other up.

im sorry that things you used to do that used to be fun are no longer intersting to you. It seems to me that in some ways, you feel like you do not have an identity because you do not have sexuality and gender to rely on and so you want to define yourself. i know at first this can seem frustrating, but i think ultimately it is very freeing, because you can be what you want to be. Think of what your hopes and dreams are in life and define yourself by those. Aim towards something you want to acheive. It will help you feel accomplishment and will help you find an identity. That is the point, making your identity and living how you form it. If you ever need to talk, you can always message me. ill leave you with this, someone wise once told me, "sometimes we must endure the worst of storms in order to see our rainbow at the end." If you hold on to your hope, as cheesy as it sounds, you can find yours too. i really hope things work out well for you and things get better.
