Trust me, from what I've seen of 'celebrity', its overrated at best. I do sometimes wish I had a better social life, though I believe my extremely rural location plays more of a role in that. I would deeply advise that you seek correct psychological aid with regards to your depression, also make sure you know the relevant helplines should you start to have darker thoughts. I'll try this, its okay to be comfortable in your own company, generally if you can feel confident on your lonesome it should overlap to social experience, please don't hold me to that though.
SC - with love.
