I know what you mean about wanting a repeat button. If I could start over, I'd do EVERYTHING differently. I don't think it's right or fair to ask anyone to decide their careers at or before the age of 18. I wish school programs could be broader than they are, in order to give students some wiggle room, but a lot of the time you get streamed into a field and that's it. It's tough. I wanted you to know you're not alone in that predicament. I'm pretty much finishing up a degree I'm only marginally interested in (because I couldn't switch into something else) in order to get into a more or less unrelated grad program I won't be able to afford but that will actually be of interest to me. Don't forget that there are TONS of scholarships and grants out there. It's tough but try not to let money be the deciding factor for your future, if you can help it.
I hope everything goes well with your parents. I know what it's like breaking the news that you want to change directions. Sorry you're feeling so down right now. Sending lots of hugs.
