Toenail health help (with feet pics)

This is very embarrassing but I need help with improving the looks of my toenails. All I want is to be able to pain them and get pedicures done. But I’m afraid they aren’t in the best condition to paint right now. I had toenail fungus on my big toes and I saw a podiatrist for that. I took a prescription for a few months and it seemed to be okay by then a few months later they were looking a bit yellow again. Not as bad as before though. So I’m not really sure what to do at this point. I don’t know if my toenails have fungus again or if they are just discolored for another reason. Any tips on how to make them look nicer? I am embarrassed of my feet. Also I just took a bath so they are a little pruned up. And my nail on my pinky toe is so small it’s almost nonexistent.
