Dear xaprilthecat,
Do not go into mental health, your intuition is telling you not to, listen to it. You are not suited for the profession, but don’t take it hard, very very few therapists that I have ever seen have the gift it takes to help others with their emotional pain. If you doubt you have that emotional fortitude, then you don’t have it yet. Maybe someday, but not now. You are 20, explore your interests. I think you haven’t found a passion yet, but it’s out there. Good hunting!
