Are there any otc medicine i can take to become happy?

I don't think so.: I don't think it's possible to take any substance and have it make you happy, at least happy in the way i define happiness. Smarter minds than mine have tackled this question. I can only tell you that becoming happy is not something you get and then keep. I also think there is a difference between feeling good and being happy. Lots of things make us feel good, the journey is what make us happy.

Happiness: Can't be found in any pill. But it does exist inside you. Enlist the help of a therapist to help you find it.
