Thank you all of you for your responses and welcoming words.
It really is a mind over matter challenge and its nice to be able to share and receive advice and your similar experiences rather than just have this battle in my head!
I'll post updates as I go. I know from the past, the next thing will be a week or two in when I start to feel really good, and that thought will creep in "I feel fine now" and then slip up and crash again for months. Cant let that happen this time.
