This is one of the hardest symptoms of depression I think. Sorry to hear that it's got you wrapped up without any idea of what to do.

If I were you I would search out new experiences, preferably something interactive and with new people. That might take you out of your element, help you form new perspectives, and maybe it'll help you reset your neural pathways.

Finding the motivation to do that is another battle, I can't say I've figured that one out.

One way or another life will happen to you and I'm sure you'll find yourself on your way to recovering from this, hang in there.
