Firstly, congrats on making it through your treatment! I was diagnosed in November 2011 and finished treatment around October 2012. It's quite a journey isn't it? I'm so sorry your husband was not supportive of you. It's sad that just when you need love and support the most, some people just dessert us. My husband was supportive, however, I did lose a couple of close friends, so I know how disappointing it is. Just focus on the positives, like the 20 plus kgs you have lost and the fact that your are now off anti depressants after so many years. That says a lot about what kind of person you are and the inner strength that you have!
As far as the fatigue goes, I have no answers for you I'm sorry. I too feel that way. I've been trying to get up early in the mornings to take the dog for a walk, but seem to lose my momentum after a few days because I'm just sooooo tired all the time. Having a job and two primary school aged kids doesn't help I suppose!! If I find anything that helps, I will let you know.
All the best
