lol DO school isn't the worst thing that can ever happen to you.
In all seriousness, if you have a 3.6ish GPA with a 508ish MCAT and good healthcare experience you should be fine. It seems as if you're aiming much higher than that and you're only a freshman. Med schools will understand (as long as you communicate to them) that you had a rough time "freshman" year, and as long as you keep your grades up, you should be totally fine.
If you're really stressed out, you can check our MSAR which shows acceptance percentiles (chance to be accepted) based on individual factors, but I think you should be fine.
