You will be ok. Your GPA isn't terrible, definitely not brutally low. Study very hard for the MCAT and make sure you're scoring well on practice exams before you take it. Your ECs are decent too, more volunteering and finding some shadowing may be helpful. Try to destress as best as you can, its a marathon not a race. You will have at least 2 gap years assuming you aren't applying this cycle, so that gives you plenty of time to strengthen your application. It also gives you time to enjoy your life, as there's still a long road ahead. Don't forget to find something to destress and have some fun with, exercise helps!
