Hi thehexman,
There's a couple options I can think of that may help you. I can't make the decision for you, but these may give you some guidance.
1. If you continue studying at your current school, you can use neuro-lingustic programming to reframe it to be a positive experience.
2. You can go to the other school. There's always the possibility that you may regret either decision, but reading about counterfactual thinking may help:
Counterfactual Thinking SSRN-The Differential Effect of Realistic and Unrealistic Counterfactual Thinking on Regret by Nick Sevdalis, Flora Kokkinaki
The best way to overcome regret is to think about something worse that could have happened. For example, if you go study physics and end up regretting it, you could think to yourself "well, at least I didn't commit suicide." That's an extreme example, but it gives a good idea of overcoming regret.
Steve's article The Courage to Live Consciously may also be of help:
