Why am I so miserable all the time?

Well, don't really follow other people.However, your personality is different from other people don't think your a maniac you perfectly normal. I mean don't feel pressured around other people or a group or friends just act normal be yourself if they don't like you how you are find another group who will. You said when you're alone you write, read, and imagine things there is nothing wrong with that at all. Other people also do the same. Don't just change yourself because everyone else is like each other. you have a talent and your not seeing it you could be a writer with your imagination and your writing skills. Maybe instead of worrying about yourself not being able to be attached to the world its not really you. it could be them. Everyone in the world have different minds they think different things. The people you hang out with maybe dont show their true color as in they dont show what they would really do they just act not their self to get along with their friends or whatever. When you said your friends lost their virginity but not you, your only 15years old don't get ahead of yourself dont get fed up dont do something just to fit in because it wont always work out and you cant reverse a serious thing like that. I would just finish school get a perfect job and start dating and get ito a serious relationship and then if you feel you want to lose your virginity go ahead if thats the one for you. dont just lose it to anyone because you just want too. Make Serious decision to serious things. Anyhow have fun :D
