Long post warning

Sorry to be posting a log story, but I don't really have mom friends or mom friends that work so I need some help.

I've been striving to a health care degree for about 4 years now but haven't been able to stay consistent with school (deaths in the family, can't afford it, having a baby.) Anyways, I've been chipping away at pre requist classes and I can finally enroll in the reapritory therapy program. But now that I'm here I'm actually really struggling with the decision. I don't know if I want to be a career woman with having my son and also with the plans on having more kids. The first 5 months of the program will be really easy but after that it will be well over 40 hours a week. That's just temporary, but still hard to handle when my baby will only be 16 months old. And I can't help but feel like this now then I won't want to work if/when I have more kids. However, working in healthcare is what I've wanted to do for so long! I don't want to give up on my dreams, either. I just don't feel like I can have a career and be a good mom. I know that's not true as many kick ass mom's work, but you know what I'm saying hopefully. I'm also very nervous about finding child care while in school because I won't be able to afford daycare. I am very excited about the idea of being able to support myself and my child if things ever went South and I lost my husband. Sorry of this sound like I'm rambling, I just have a lot of pros and cons. Does anyone have any advice or prespectives? Husband is supportive no matter what I want to do.
