Lola, I'm new to depression in myself but have been with my wife who had it for many years until she recently passed on. She often said she was able to deal with her illness through getting to know and be comfortable with herself. Initially I used to feel offended but I came to know what she meant. We must be comfortable with ourselves so we don't "need" others. They sense that need and run away from it you see. My view. Friends come and go, that's for sure. Looking back I can see why and it is mainly because I have changed or moved or got a new job, got married and so on. Once I made a change like that my friends at that time in each situation suddenly had nothing in common with me or I with them. Getting married was a commitment I chose and it meant spending time with who I loved and not hanging out etc with others. So of course we lost touch.
I guess I'm trying to say the important thing here is to have your depression treated and recover enough to be an attractive person as a friend. Superficial it may be but people just are scared of depression cos they don't understand it. I didn't until recently and probably still don't know much except through my wife's eyes and life. So rejection as a friend is usually not rejection of us, it is rejection of the illness. Which makes people seem ignorant when they are really just scared. We don't see that as we are so scared ourselves. Right?
Work on your treatment and read up on CBT.
18percent. Writer's block? Or is it depression taking away your interests. motivation and focus etc so you don't have the mental strength to actually think of the plot and write? I've had writer's block my whole life as I've never been able to write for myself. I can here, out of misery and a need to talk but at home by myself? Never even tried, haven't got the insight to do it. So be glad you have the ability to write as it will come back when the depression lifts.
