As an update,
after writing this, I went outside to walk the dog and I felt so annoyed with this blockage, so so annoyed - what is wrong with me?! I refuse to spend another day (off) at home doing nothing! -I looked at my dog... saw those pretty eyes so resigned to walk the same walk again and I just said enough! Let's go, dog, let's go to the beach. I went inside to get my things. Did it fast before I regretted and the momentum was gone. And to my overthinking I said "screw you!". I have money, I have gas, I have time, if I get there and it's dark, then I come home, but I'm going, if it's crowded and I can't go with the dog, I go for a walk around, whatever. I'll just go.
I did. My dog loved it, it was great. I felt so proud! And I proved myself that it isn't hard. It doesn't take that much energy. And it warmed me up to go back.
I guess I was falling in the habit of not going. And forgot how relaxing actually is.
Was it a temporary burst of energy? Hope not.
