Feeling like ?!! Rant!!

I am 36 weeks and I am exhausted! ? I am a full-time student on top of having a almost 4 year old ds. I recently left my husband and am working my butt off to try to keep from touching savings while I'm out on leave. I can't get comfortable to sleep. I wake up multiple times a night to go pee and now I'm waking up multiple times with contractions. I just want to sleep!
