[...] yes it is hard, rough, and it sucks. Your story may be better than mine. I did it, others have done it and many more will do it.
First make up your mind and Decide and believe you can do it.
Then make out a thoughtful, and workable flexible plan and then start. Listen to your body and take your time. And realize it will take time to do and heal.
Lots of wonderful people on this forum.
