Time to smile

Hi! I'm trying to raise enough money to get my  mouth fixed. Chemo destroyed my teeth years ago. I havent smiled in over 15 years. Im so depressed. I can't eat,smile or talk properly. I would love to get the all on 4 as mydream but i really want  just to get healthy. Im constantly fighting infections and am in pain. It has taken months to get a picture. Im so embarrassed and hate asking for any help. Thanks for reading! I forgot to add that I  do need some sort of implant to hold the top on place. I have a bone up top of the roof of my mouth and it doesn't allow enough surface for an upper denture to suction on. Or it will make it harder for it to suction on. Thanks again!
