Help with Mobility Items

Hi I am a single mum to 3 sons and I'm unable to work due to my bad health. I suffer from Fibromyalgia, Slipped Disc, Osteoarthritis in my spine and knees, Asthma, Underactive Thyroid, Supraventricular Tachycardia, Fibrocystic Breast Disease, Chronic Migraines, Malignant Otitis Externa, Pedal Oedema, Depression and Anxiety and I am now going to see a Neurologist to see if I have MS. I get disability benefit but only the low rate and it's barely enough to live on and pay the bills, I owe council tax and other depts so can't afford to buy anything else extra. My sons are my carers aswell as going to school and college and I hate it because they should be with there friends not helping me. I would love to get a Mobility Scooter then I would get some Independence back in my life which will free up some of my sons time.. I would also like a perching stool for my kitchen and some other small Items that would help around the house ( Electric Tin opener, A Kettle that is on a stand so making it easier for me to tip ect ) ... If I got a mobility scooter I would need a shed to put it in so it's not outside because I haven't got room in my house to store it. I live in a small village so I know it will be safe in there. Thank you for taking the time to read this and would like to help me I will really appreciate it.
