I would tell you this; I’d estimate the vast majority of MT students currently enrolled in college programs got rejected by two schools. It is difficult for many because there’s a lot of kids that were the big fish in the small pond, got all the parts (my D went to a huge high school so she actually was more used to not getting roles than some), and when you get rejected you may not have had that experience before and don’t know exactly how to deal with it. But it’s far more the norm than not, so I certainly would not let two rejections after prescreens have you question whether you have a chance. Sounds like you have other good schools on your list, good backup plan, etc. so keep your chin up!
I will tell you the same thing I told my D when she got her first two rejections (one from one of the same schools you did): you can do theater and perform the rest of your life, what you are not sure of yet is whether you will do it for a living or for a hobby. You don’t know that yet either. What you do know is you have at least two schools that see enough in you that they want to see more, and you do know that you have other interests (psychology) that you would also find passion in pursuing. And that’s a pretty good position to be in.
Sitting down with parents to discuss, counselors, etc are all things I would advise. But in the end there’s really one question to ask: if you abandon your plans for studying MT now, will you look back and regret that you didn’t take your shot? There’s many here that can help you with school lists, provide advice and encouragement, lend an ear, and we veterans are here to do that. But only you can answer that question.
Break a leg. You’ll make the right decision for yourself, I’m sure.
