I would say that a problem I have had & still have to a certain extent, is to do with self confidence (well the lack of).
I’ve aways been a reserved person but this was highlighted even more when I went to Uni. I found it quite hard to make friends & push myself out of my comfort zone, which in turn led to me being rather lonely.
This is probably when the self confidence issues started to creep in.
When you are alone 95% of the time, it becomes so easy to get trapped in your own head & be consumed by self destructive thoughts.
There would be times where I wouldn’t leave my room for days due to crippling social anxiety & the fear of being judged on my appearance.
I still find it quite hard to socialise with people, especially those I don’t know but I’m not as bad as I used to be.
