Can't say I've ever really let things bug me to the point of depression, I don't get it, I mean I've had sadness due to people dying, losing two babies and such but I don't fall into depression over it. I'm saddened, I'm distraught but I move on and try to keep my life going, I've been in a few fights, I've been covered in another persons blood which has made me have to go on ARVS and yet life goes on.
You either go see someone to assist you, or you just wallow in it, it's up to you. Sorry if it sounds harsh.
