I am stuck in a funk right now too. I know things I can do to make myself feel better, exercise, cooking a good meal for myself, calling a friend, but just getting the energy to do those things seem impossible sometimes. Finding a hobby to do to take your mind off of things works sometimes too.
What has worked in the past is setting up a schedule, and then putting alarms in my phone. For example, 8am - daily goals journal, 10am - meditate for 10 minutes, etc etc...it is a good reminder to sometimes snap me out of it, but lately that is not even working.
Maybe set up structure in your day, so you can't just wander aimlessly around the house.
WH sees getting things done as part of his remorse expression. So, he makes himself do it even when he doesn't feel like it. And then afterward, he feels a little better bc he did.
Maybe if you looked at it that way it would be more motivating?
Its easier said than done because we caused the issue. I try to think positive and keep my mind in positive thinking, but knowing what I still did it hurts and I get stomped back down to the ground.
Just keep going and be positive, what I learned from my Buddhist meeting is that what you feel on the inside portrays everything on the outside because it reflects how you are on the inside. So be positive and it can help.
