So many questions

[unsure]

Hi. I'm new to this so bear with me. I have so many quesions that I just feel overwhelmed. My husband and I are in the begining stages of talking about a divorce but it has been on the horizon for some time. The problem is that I'm a stay at home mom and have been for 4 years. I now work part-time but it really amounts to only spending money, I have no idea how to even start again on my own with no money etc. Plus we have 2 kids aged 3 & 9. Anyway even typing all of this out makes me feel a little better, I don't get to vent much here at home.
