MUSCLES WEAKNESS

Hello everyone!
I'm proud that i finished this program months ago, and my symptoms really faded away except in some conditioning situations.
In these past months me and my family went through some changes and difficult situations in life, there was a lot of stress and i couldn't find a way to find a time for myself to just reflect and listen to my body. I still find it difficult to schedule time for me like I'd like to repeat the program and i don't know how to deal with commitments of daily life and with this. WHEN i began this program i was free just focusing on myself because i didn't have any job or anything now it's different!
also i have a question; my hands and arms are somehow weak due to years of doing nothing because of pain, and i don't want to think they are weak but they are, and i don't if just training and exercising gonna help or just changing the way of thinking about this matter.
