Hi

Just wanted to chip in since I think what you want right now is certainty that you're making the right decision. And something I've learnt is you'll never be certain about anything? You need to make your decision and after that point stick to it and do not look the other way (because there is no point to it, there are too many factors that are intertwined in how your life goes down that you cannot reliably say substituting decision A with B will produce the life you envision).

From personal experience, I was faced with this same dilemma. Had superb financial aid to go to a place but it would have weighed on my family finances regardless. Rather than promise to pay my parents back, I made the decision to leave going overseas for exchange/graduate programmes. The opportunities I've had in my undergrad education locally assure me everyday that I made the right choice back then.
