Hi, I'm looking for some advice please.
I'm morbidly obese with a BMI of about 46. I'm 5ft1 and I weigh 17.5 stone. I struggle with my weight due to eating crap, comfort eating, convenience eating due to disabilities and no exercise.
I have fibromyalgia and a spinal injury, osteoarthritis all over, cervical spondylosis, Peri-menopausal, celiac and ibs. I'm 35 
I know I need to change my diet. Due to the fact that I'm in bed most of the time, I find it too hard to go downstairs, stand and make food. This means I'm eating sugary cereal for breakfast, a sandwich my husband leaves me with crisps and chocolate, a couple of pieces of food and then a takeaway or something that can be oven cooked quickly for tea like gf nuggets and chips, steak and mash, ready meals etc. My husband is ill himself and works full time so can't spend much time cooking.
I'm now finding it difficult to just move the minimal amount. If I go downstairs and walk back up I'm incredibly breathless and my heart races and pounds. Even walking to the bathroom leaves me breathless.
I really want to tackle my problems but I don't know how. I have severe health anxiety so can't see a GP because I can't leave the house. My blood pressure is fine. If I start moving around and I feel my pulse elevate I have panic attacks. I'm limited to what I can do because of neck and spine pain and knee pain.
I'm so, so miserable and scared. I can't seem to get a grip and make healthy food choices but then we never have healthy food here. My husband does the shopping and he's underweight so buys junk. DD eats healthily but is starting to notice my poor choices.
What can I do? I've spent the morning in a state of extreme panic because I walked up the stairs and I thought my heart was coming out of my chest.
