i am always down and can not seem to keep friends anyone else

i dont know why but recently i have turned to and relied on drugs to make me happy until i was caught.
the reason for being so unhappy is coming from lack of friends as i transferred to a private school and they all are very full of them selves and pay no attention to me they only bother me when they say unkind things to me and push me about i just get so depressed and so frustrated!!! I also have a pregnant mother does anyone else feel this way?
