You are not alone, @Becjax. Many of us here have experienced the same thing. Personally speaking, I feel invisible when I am at home and sometimes even when I am at work or around the few friends I have these days.
My life has been so internalised that I often feel as though no one can really relate to my experiences, so I stop sharing, I stop seeking help, and I just kinda fade into the background.
I think this is probably part of the reason why I suffer so badly from depression.
I am still very new here myself. Please don’t think you are alone. Just chatting with others will help and if what I’ve seen here in the few days is any indication, you will find many people open to discussing their situations and offer their own insights. Hang in there. You are on the right path now.
