weird problem with my attitude

Not having any interest in anything and not being able to sleep couldbe a sign of depression or anxiety about something. It's hard to say without knowing very much about you. It could just be that you are different in what you like from your friends, which is ok . When I was growing up I did not want to go to discos etc with my friends but preferred to sit and read books. I still prefer to be out walkng in the woods with my dogs rather than shopping for clothes and I just like to wear my jeans and t-shirts rather than some fashion piece and I don't care about designer bags etc I'd rather give my money to the pet shelter to feed the animals. I don't know how you are feeling different but if it's anything like I've descibed then it's ok to be different and maybe you just need some new friends who share your interests. I used to get depressed worrying about everything like people starving in Africa or the many wars going on and thinking I couldn't do anything about it but I realised that I could help in a small way by helping at my local meals on wheels place or helping at the animal shelter. Don't worry if people make fun of you because you are different. People made fun of me because I had an old car, not a new shiny one like theirs but I didn't have a car payment so I could save more and get my own house instead of renting somewhere, so for whatever reason they are making fun of you, tell yourself that you like and believe in what you are doing. You won't get peace of mind by trying to fit in with everyone else if you don't like what they are doing or believing in. Just be yourself, do what you like to do and make yourself happy.
