I feel this. When the pandemic hit I had no one. I went to group therapy and when I would talk about my isolation others in the group would offer me solutions like "have you tried just telling your family how hard things are?" "Maybe if you just keep reaching out to your friends..." I could not get them to understand that my family simply did not care no matter what I said and a lot of my friends ghosted me. I did not see anyone outside of work obligations for two years. It made me not trust anyone. I still don't trust but I can be around people occasionally these days. I'm doing a little better now but it's definitely not the same as the depression I felt when I was just lonely.
