I know all too well where you are coming from. I was originally diagnosed as a teen and went through many years being sad because "i can't" in my late 20s it just because a part of life and was in one foot and that was life. Until this past December when I had to have surgery.....I miss my life every day. I am sad, bitter, angry, on edge, hopeless, etc all of the time anymore. I enjoy nothing really because nothing is the way it was. I cant work, I can't drive many days, I can't focus, I can't remember things, I cant be nice because I'm so exhausted and have zero patience, etc etc.....I'm very stuck on "I can't".....I wish I had words of encouragement......however, one of my dear friends has MS and he is much worse off than I....I need to be grateful and I know it.
