I went through a very intensive 18 month paramedic program when my son was two years old as a single parent. It was tough, but it can be done. I was in a position where I HAD to do it...I had nothing to fall back on. I had family support, but had to be creative in my own ways. I was blessed with a vary patient and understanding child, who rolled with the punches, and that made it easier.
I started nursing school when he was 14 (and I was still single). In a way, that was rougher, if only because of the scheduling nightmares we had to work out. He was very active in dance and theatre, and I had to figure out how to get him to shows and auditions, plus his school, plus my school plus my work. Keep in mind that teens do become rather needy little parasites (
