I've had ME for 6 years. Had a full-time job and like you lived life at 100 mph. I eventually lost my job, was housebound for a long time, had an attack of severe OCD, things were pretty horrendous.
6 years on I'm still unable to work, I sleep a lot, have very limited mobility and can't do a lot that I used to BUT I have a life. I fell in love and am getting married next year. I've learned to sew, knit and crochet. I enjoy listening to audio books. I pootle around on my mobility scooter playing Pokemon go. I have friends who I chat to online or meet for cups or tea, go to knitting group. This afternoon DFiance and I went to a bird of prey centre - barely moved from the sofa since getting in, really worn out, but I went, and i loved it.
What I'm trying to say is it's been horrendous, but it's not stayed horrendous. Even though I'm still ill. When I was diagnosed the specialist doctor said I needed to "reassess my view of my future life" and he was right. I hope things improve for you, i really do, but with peace and pacing and loving family and friends, and a few supplements, I've got to a point of acceptance (NOT giving in, but accepting this is life at the moment and it would be a waste to not live it somehow - I have been working with a physio to improve my ability and do gently push myself) and have a life.
That might sound..I don't know...preachy or trying to make it sound to easy, and i know I've been very lucky in the support I have, but I guess I'm trying to say that there can be hope even if you don't recover. Life is different but it is life.
