Gave up working in a office when I had my second child, had a tough time with pregnancy and didn't want to go back as they were unsympathetic, working in eve's in a garage, I dont enjoy it and feel very unfullfilled, have two children one aged nearly 4 and one 18mnths. My dream is to become a teaching assistant when daughter goes to playgroup next September, am I being unresonable for feeling trapped if i stay or face doing my dream and incurring childcare costs, or continuing being miserable for the next couple of years in a job i hate, please advise.
