Is this athletes foot?

Lately my feet have been SUPER sweaty and stinky from having to wear the same shoes at work every single day (I make $14/hour & live on my own) so buying multiple shoes really isn’t in my budget rn :( what can I do to get rid of this? It was worse (had more yellow and flakes) a week or so ago the only pain I get is from like a callus inbetween my toe which i think is from a new pair of shoes that aren’t wide enough for my feet.

Anyways please help me get rid of this before I gets worse (I also don’t have health insurance atm so going to the DR also isn’t an option)
