For me, happiness is being free from all of my mental diseases, and living life without any limits. Taking risks and actually living life the way I want to.
Happiness is having the freedom from the constraints and fears of this life. Being able to be at peace with my mind and have found that I live truly and fully to my principles no matter the situation yet still functioning with society. It is to have kept my promise and paid my debts. It is freedom from myself.
Having meaningful relationships with people; actually feeling loved and loving, being around people that don't care what I look like. I'll be happy when (more likely IF) I have a family of my own.
Being free from jealous, irrational, insecure, paranoid thoughts as much as possible. That also involves not questioning people's motives or second guessing things, or comparing myself to others that leads to feelings of inferiority.
Being contenttttttttt, but consistently. If I'm happy for half a day, and then an emotional wreck for the next part it just makes me feel worse being up and down. Consistency would be nice.
Happiness is finding out that a scientist has invented a time machine, and I can travel back in time to the day before it all began; taking with me the knowledge I have now.
Having a normal day where I dont have to battle my negative thoughts and can treat life as it comes,without being so depressed I assume I cant ever be happy.
