hi kat
imo some pretty spot on responses in the posts above.
re: a career in research - as antisense said, it certainly sounds like high stress trying to get funding from all the people i know in various fields as well, and it doesn't always sound fair or just in terms of who gets their share of the pie - but hopefully your eventual field hits a period of high interest and some funds come online. sounds like you have all the rigght ideals in mind for long term interest and enjoyment/fulfillment. kudos!
just wanted to share story of a close friend of mine as well - she didnt finish high school and worked for 8 years or so after dropping out for personal reasons. decided she was really interested in health and nutrition - got into uni with some bridging and tests, finished with first class honours all while doubting whether she was good enough to be there, did volunteer work at a clinical research group, and when they asked her to do her honours through the same medical group she jumped over into an even more prestigious uni. now is half way through her phd and is the hardest working student i have ever seen, always going above and beyond because she loves it, but also able to relate to people because she has gone out and worked and is not overwhelmed by real life situations... in 1.5 years she will technically be a "doctor" but i think will still be that unassuming person who loves studying and learning for its own sake and will still be pinching herself that "real doctors" value her opinions on her field of expertise. mature, committed learners are the best kind of students i reckon.
go for it - live and breathe it - give it your all! (but save a bit in the tank for wind and waves

)
ps. +1 to underoaths story too - hard working (18 year old) male student is an oxymoron

from lots of fun experience
