I have a major weight issue

due to medication and lack of exercise due to the fact I have M.E/CFS and cannot do vry much due to pain fatigue and muscle exhaustion. I need to do something as my health is adversely affected by carrying more weight but being home all day and having a sweet tooth dont all add to the ideal situation for dieting. I have considered joining weight watchers or slimming world but nothing will work till I can quit eating the cakes, biscuits and crisps, Problem is if my husband says anything i get defensive and upset. I will try extra hard to get myself in order before i turn into a beach ball

190lb is too much for a 5ft 5inch woman.
