Upset

Before I got married, I wanted a career. I took out a ton of student loans to get my degree. Now, I teach a high needs special education class. Last summer, my husband and I bought a house at the top of our price range. Needless to say, I have to continue working once our son is born. Lately, I've been so upset that I can't be a stay at home mom. I don't want a career anymore. I just want to spend time with my baby and give him a mother that isn't emotionally and physically drained all the time from work. I'm literally sitting in the bathroom at work crying as I type this because I'm so upset. Has anyone else had this struggle? How did you get through it?
