alone

i am an adult living with spina bifida and I feel kinda of silly posting here because my problems are'nt really that bad but I don't have a good support system. I have been working as a cashier for 4 years now and it has been really waring me down I would like to quit but then I wont have insurance and i need insurance I have looked for othe jobs but so far have been unsuccessful even though I am a very hard worker is there any one out there who might have any advice
