Hi guys,
I suffer from depression but I overcame it for a long while and did fine. I'm always doing very well and I am not depressed at all when I am single. But always when I meet someone I get depressed. Now I am in a relationship that seemed very good in the beginning and I, myself, was doing well. With time I sinked into my depression. Now we fight a lot and mostly because I always find a reason of not being happy. Sometimes her reaction is also not the best one, but maybe she's just sick of my reasons to fight. I end up overthinking how bad this relationship might be and in the same time asking myself if the relationship is the problem or me trying to sabotage my relationship because of my mental state. 
I was done with therapy, but I will start again next week...
Anyone else struggling with something similar?
