L.G.
Stick with it! I went through the same thing when I was finishing my masters degree. I was having a difficult pregnancy, and then when my daughter was born she had a birth defect that required a lot of travel and doctor visits. I also had 2 semesters left, and everyone encouraged me to drop out for a while, even my academic advisors.
But I didn't listen, and I'm very glad I stuck it out. Now that my daughter is older, I see that it only would have been harder to go back if I had waited. At least when she was an infant she slept a lot. I was totally exhausted, but I completed my classes online while she napped and after she went to bed at night.
It won't be easy, but you will feel such a sense of satisfaction when you get that degree! It felt great to accomplish something people told me I couldn't. Keep at it and good luck! You can email me if you need any moral support.
