The past few months I've been trying really hard to suppress my feelings but I really can't anymore. So here it is, I'm very very very lonely and bored. I'm still a teenager and its been a year since I've dated anyone. All my friends are in a relationship and are really happy and totally oblivious to me. Its been making me feel left out and lonely and I don't know I just basically feel worthless most of the time. I've been crying myself to sleep and I don't even know why! I know that I should really let it go and try and enjoy my life but these feelings just aernt going away anytime soon. And to top it off I feel like my best friend and I are totally drifting apart because she's dating my brother and all she wants to do is hang out with him but I really DO NOT want to hang out with my brother and his girlfriend! I try to shut myself out and just study or whatever but my mind is constantly distracted. I Don't KNOW WHAT THE HELL I AM SUPPOSED TO DO! So if anyone can help me figure this and these feelings out please help!

Do you have friends who are not dating? What about after school activities or hobbies?
Busy yourself with fun things, get to know different people.

I do but see nowadays we have a lot of tests and stuff so Ive been studying a lot and I don't really have too much time for extracurriculars between music theory which is seriously boring and studying. In whatever little time I DO have I would love to just hang out with my mates , you know go shopping, catch a movie and stuff, but they're always bringing along their boyfriends or whatever and I end up getting seriously bored. And Ive tried explaining to them and they're like " Im studying the whole day its the only time I get to see my boyfriend/ girlfriend"

Go out with people who don't have girl friends or boy friends. Make some new friends.
