Think I got a stress fracture

Started running a couple weeks ago, I’ve always done really low impact stuff like walking and swimming but of course I had the beginner mindset that “I can handle it, it won’t happen to me!” Now my foot has been hurting and hasn’t gotten better after 5 days of rest. I know I’m gonna have to rest it for at least a few more weeks but I’m super bummed. Also worried that once it feels better I will have lost the motivation to keep running:(
