Help me get some sort of normality

Hi,im a single mum of 6. 4 boys and 2 girls. After my last baby i became disabled after catching necrotising fasciitis after the c section. I also have a huge hernia due to a weak stomach wall from the illness and so much surgery. Since last year i havnt been able to walk for more than 5 minutes without severe pain and breathlessness (i have copd too). For some independence i bought a mobility scooter to get out with the kids especially the younger 2. 5 weeks ago the scooter packed up and due to being second hand wasnt insured or guaranteed. I have no way of paying for a new one and would be so greatful if i could raise funds to buy a new one and have a life again.i havnt left the house in 5 weeks,my depression had got so much worse due to not being able tl do anything with the kids.the youngest is due to go nursery soon and i cnt even take her.if anyone could help a little to help me get my life back it would mean the world.this is literally my last resort. Thank you xxx
