Re-app chances?

What do you y'all think are my chances at getting in? Any input's appreciated, I need all the advice I can get!!! I'm a re-app, but my stats haven't changed too much. 3.53 cGPA and 3.41 sGPA with a downward trend, save for the last few classes I took in undergrad and a class I took for fun a year ago. 512 on the MCAT that I took in 2016. I didn't get any interview invites last time I applied, and my application was limited because I was underprepared and didn't get a doctor's LoR. Quite my... Re-app chances?
