You are right to feel that way. Remember when we discussed how exhausted both of us were feeling a while ago? I think this is all part of that same process.
So much of this is mental. I believe the exhaustion is also mental - i feel it almost every day.
The challenge is to figure out how to calm your brain down. I cannot really help you there because I am still figuring out how to do this too.
But I can relate to what you're feeling.
This isn't easy but you're doing great. Take it easy on yourself, man.
