Hi Donna and welcome. Some days are just so tough with the pain and fatigue. I completely understand as I suffer from it as well. More not-so-good days than good days. I also understand the fear of going back, especially with the brain fog. You say you want to go back a couple hours per day, but you feel you've lost your confidence. Well, the only way to overcome that is to just do it. I always try to think of the worst case scenario. So, for you....What is the worst case scenario? You try and go back for 2 hours at a time and you continue to have memory issues? Then you are no worse off than you are now. So, if you start back for 2 hours at a time and it works out, then GREAT! It's forward movement. If you try it and it doesn't work out, then you know you need to come up with another solution for income. It's still forward movement. Those can be tough things to hear, but sometimes just doing something whether the outcome is what we want or not, can be easier to deal with than being stagnant and doing nothing but fret.
I hope this helps. I don't want to stress you out worse. I'm a pretty direct person, but also have a lot of compassion. Gentle hugs....
