Extremely emotional - 37 weeks pregnant

This past week I have been so emotional, I feel like all I’ve done is sit, overthink things and cry constantly. I have felt so down, I feel like it has begun ever since I started maternity leave. I just feel like a waste of space, my boyfriend gets up and goes to work Monday to Friday from 7:30am until 6pm so I only get to spend a few hours with him at night throughout the week and at weekends, which makes me feel so lonely and I miss him like mad😩 I also keep thinking about when our baby is born my boyfriend will get 2 weeks paternity leave, so we will be in a bubble filled of love with our baby but after those first 2 weeks, I will be left on my own with our newborn while he is working for all those hours, that will be a killer😢 I just feel like crap about myself completely, I’m used to getting up and going to work, being more energetic and busy, but now I just lay about feeling lazy, miserable and useless. I honestly feel like sh*t about myself! I have already bought everything for my baby, my hospital bag is packed and all of the babies clothes are washed and put away into drawers - which I’m glad is all done, but I’m left with nothing to do other than sit around, overthinking, crying and feeling like sh*t😒 I have had a few days where I’ve got up and cleaned for a few hours, gone shopping or gone out for food with a friend but I find myself needing to rest afterwards because I feel exhausted and that’s when I find myself sat thinking and getting emotional.

Anyone else feel like this?
