Obsession Problems

Hi all, Have been gone for awhile but need advice. I have been diagnosed with depression and anxiety plus avoidant personality disorder. Won't go into all of it but doctors think it is part biological part environmental. Every time I think I get a handle on things, I end up relapsing.

One of my biggest problems is I tend to fixate on one thing to the exclusion of other things. For awhile it was politics, now for the past couple of years it's been a silly TV show. Then when things don't go well or are even rumored to be going unwell I get nervous and sad. Believe me I know how ridiculous that sounds. But lately all I do is obssess about it.

The thing is I am on disability and most days don't have anyone to talk to but my sister at night. I don't fear going out but I do fear driving and only do it when I have no choice and I don't live near a good public transit system. So talking to people on social media is kind of life line for me, and lately it's been talking about the show.

I am in treatment, they've tried med changes, it just seems I am going backwards not forwards. It all seemed to get worse after a bout of viral meningitis last year. Any tips or suggestions. I am really struggling here.
