My friends don't appreciate me. What should I do?

You have two options, either let yourself mature and change so you are not so dependent on being eccentric to attract attention (read childish and self centered) or find a coupe people who are more like you and see if you can be more comfortable getting to know them and developing some new friendships. Making good long term friends takes time so don't burn your bridges or jump ship all at once, some of those who are bugging you now may have an emotional growth spurt soon and be sorry they were mean.
