I do believe that you can do it.
I was in your shoes years ago. I went back to school after I had two kids! My hu*****and did not care about my career. My parents_in_law againsted me at that time! They even went back to China, thought that I could not handle two young kids (3 yrs & 4 months). I did go to the school to get a degree I wanted. I just brought my kids with me to the school. While I was in classes, they were school day care. I finished my school at the same pace as other young students with Honors.
What I want to say is: if you really want to do it, you should be able to do it. Believe yourself.
10 years past, during those years, my hu*****and got laid off several times. I got promotion almost every couple years. I am so happy that I can support my whole family during all the hard years!!!!
You can do the same
