I hope this change of yours go well. If there is ever something I can help with, tell me.
Of course tho, you have just realised you want the change. Now you have to orient it.
Kind of like, how I felt by early February. I was somehow permanently in a bad mood, and I was absolutely torn apart by Engineering. I felt something was wrong. So I thought I'd need a change. And then I thought "I could go to Australia for a few months after summer or something, I must change, put things in perspective."
Then I went to this psychiatrist, friend of my cousin-once-removed, or something and well she does that, she guides people towards professional paths most suitable to them. And in the end I went for a much smaller change such as switching to English Studies.
The question for you now is, what change to make?
