DD nearing the end of 1st year uni, doing maths. She has never known what she wants to do. Every time a door closes to being able to choose something else or whenever she's stressed, she seems to drop into a depression for days/weeks moaning that she's chose the wrong subject and needs to change.
First time she did it, was a week after she put her UCAS in, spent ages researching other options, then decided to stick with maths. 2nd time was when she was stressed about getting assignments submitted in her first term, again spent ages saying she was going to drop out/change course/start again. She even went to some computer science and electrical engineering lectures in Jan/Feb to help her decide, but decided she wouldn't enjoy it any more than doing maths.
And now, yesterday, she had an exam, thinks she's failed (she always thinks she's failed, but never has) and yet again, she's crying on the phone at me for hours, texting me, saying she's going to change to chemistry (she did it at A-level but has never shown any interest in doing it at degree level until now). I know she's only saying chemistry because a housemate of hers is doing it and loves it, but that's him. It was the same with the computer science & electrical engineering - at the time she knew people doing those subjects who were very happy with their choice.
I've told her to take a couple of years out/drop out altogether (doesn't want to), or change if she wants (doesn't know what to). But she always comes back to deciding to stick with maths anyway. I was really sympathetic about it at first, but she's just driving me mad now, and I really don't know what else to say. I think she just suffers from massive "grass is greener" syndrome.
