I have been there too! It is a miserable place. My T says to try to focus on healthy diet, exercise, spending time in nature, fresh air, and doing something you enjoy.

Sometimes I want to smack him when he says those things and tell him - I can't! But I have found he is right. Start with small steps, getting out of bed and showering and each day try to add a little bit more.

It sounds impossible and overwhelming, but the depression will continue to pull you under until you actively try to counter it.

Be patient with yourself and hang in there

Hope this helps
