Thank you for responding to my question!
My turtle does have a heat lamp, I think it may double for a UVB lamp but I'm not sure, if not I can get a UVB lamp ASAP.
I will try the tough love diet like you suggested, I couldn't get the clip and lettuce today, but I have a two week winter break and plan on getting it in the next few days.
I've seen the ATBA's before, and I have two family friends willing to try and make one for me, but one of them just got injured recently and won't be able to do it for a little while. Neither me nor my mother are very handy, so we won't be able to make one ourselves, so it won't be immediate.
I took some pictures of my turtles shell and eye, and I'll upload them now, but I'm not very tech savvy so it may take an hour or so lol. Her shell isn't soft, and it doesn't look like other pictures of shell rot or anything, but looks kind of like it has teeny tiny white dots, like dry skin almost. I'll upload the pictures today.
Thank you for all your help so far, I was a little worried nobody would respond.
EDIT: I have the pictures, I'm really inefficient and made them all print screens, but here they are nonetheless:

Is the shell OK? What should I do if it isn't?
2nd EDIT: I'm worried about the white-ish skin on the top of my turtles head as well, that's been there a few months, is there anything I can do about that?
