Need help with things

I assure you I hate this position and asking for money but sometimes its need ed...I've got 2 things going on. I am currently in hospital about to have a foot amputation. I can't put any weight on it whatsoever after surgery for a few months.  They have these medical scooters I can put a knee on and get around to be able to care for myself. My insurance won't cover it and I have no idea why. I'm already disabled and get a small payment every month after child support but I do what I can. Also some of you may know last summer I totaled my car sitting a trash truck. I had a seat belt on but broke collarbone and chest. I need a reliable used vehicle with an automatic transmission.  The loss of this foot makes using a clutch obsolete. I am going to have many dr appointments and it's just too mu for my elderly mom to always take me too....I'm not trying to get a hot rod just something cheap and reliable... please if you can help I would be forever grateful.DO NOT DONATE if it will hinder you please but if you have any extra again..
Thank you I will keep this updated as available. Thank you for reading this,Robert
