PT Job@ 30 doing what I love?

I need some help and advice. I am working FT @ a local school and making double digit money but am unhappy, I just applied to an online school to get a degree in Exercise and Wellness which is a field I love and want to get into to become a personal trainer/coach...problem is I want to take a job for less money or less hours(PT) to be happier while I complete this schooling. I currently live with my mom and give her rent money but I know this won't sit well with the opposite (i've been single/divorced for 6 years now) and I do really want another place of my own...my sanity is important to me but I just do not know what to do. I do not wanna be single another year or so while trying to finish this degree and being a prt-time worker living with my mom at my age just for the sake of my happiness...do guys even respect women like this???
