I had the same problem(maybe ,still have...)i always looked negative through everything.Sometimes,i even hated my innocent little brother because of my unnecassary and silly blues.
Then,i found myself another things like to do like sports,music.For example,i discovered this site and had friends.I changed some of my friends or tried to do as if they werent there.Then,i fall in love
They really worked.Now,i am happier.Of course,i have some hopeless spaces inside of me.But it is so hard to make anything perfect.
