Am not surprised you feel like you do. You have myeloma and holding down a full time job. That must be exhausting with all the drugs as well (and all the time spent in having the therapy).
Cut yourself a big of slack and allow yourself to feel rubbish. I am retired and am in the position where I can flop if you want to. Certainly could not do all the stuff you do. Hopefully this will gradually pass and your remission will mean the fatigue etc will ease. Don’t give up!
