I want to pop myself! Uncomfortable and can’t sleep.

I feel so bloated I want to pop myself. I am due on my monthly tomorrow. On the plus side I found my ultrasound letter and discovered that my ultrasound appointment is actually on the 19th rather than 15th (don’t know why I thought it was on that date) so definitely will be done with monthly by then. I feel sick, the scales are just insulting me every time I get on them (cut daily calorie consumption two days ago by 400 to 300 deficit a day depending what I eat so hopefully that shows on the scales after a few weeks) and my allergies have kicked off after being ok most of the day. I keep getting frustrated and the brain zaps are now on and off. I want to sleep but I can’t. I managed to catch up with some sleep yesterday for most of the day so at least I got some. Even when I do sleep I keep waking up every few hours. It is really annoying. I don’t know if it is insomnia, antidepressant withdrawals or the mattress being uncomfortable. I don’t know where to put myself. I need to be up tomorrow to get parcel back and my nails need doing because they are growing out. I caught one on something today and it really hurt. I am having them taken off for a while. I have my own nail growth underneath which are a decent length if I can prevent them from breaking. I hate the feel of having them taken off but these sets start getting uncomfortable after a few months of nails growing underneath. I had them on since March so nearly six months.
