I myself suffer from social anxiety disorder, which started at an early age (probably around 9, if you can believe it!)
I put on weight as a kid, got bullied, became more reclusive, got bullied more, put on more weight and thus the cycle repeated itself
As a result, I've not had any life, at all, I've only ever had one girlfriend, who was very tolerant of my insecurities and anxiety, but I just couldn't be with her and feel comfortable.
So fast forward to 32 and I have ZERO friends in the local area, because my anxiety and weight issue means I don't go out.
I used to play a lot of online games, so met some wonderful (and plain horrible) people online, I'm lucky to call two of those friends, "brother", because they are the closest thing I have to real siblings, sadly, both of them live in the USA.
So now I've told them about my depression, while they are supportive, they of course feel rather powerless to help
And as I've started to try and confront the depression and anxiety, I find myself feeling more depressed and more anxious, because I feel like it's too late.
