Does anyone actually feel happy with life in general?  Sometimes there are fleeting moments in which I am happy but over all I seem to just be an unhappy person. I've been with a guy for 6 months and I have tried to let him get close but I keep thinking negatively about the relationship. Why can't I just be happy?  There are so many people out there that have way worse problems than I do but still I can't seem to let go of the negative thoughts.  I am on meds and went to  DBT some yet nothing seems to help. 

Any suggestions on how to find happiness?
