Very sensitive to touch, pain, blinking

I had extreme emotional pain before bed tonight. It was unbearable. I tried talking to my partner after kidlet fell asleep. I asked if I could talk, and within about 45 seconds he started looking at his phone. I was angry, mentally exhausted and in a lot of emotional pain, but sleep finally came.

My child has been extremely clingy during isolation and is sleeping in our bed. I woke up twice tonight with him running his feet up my legs thinking it was a rat in the bed. I have ZERO space of my own during every waking and sleeping minute of every day. I work full time from home right now during iso in a demanding role while taking care of our kidlet 24/7. Most of the time I'm on my own because my partner (who said he doesn't love me anymore recently) goes in to work. I won't even go into what my lunch "breaks" involve. None of my friends are in contact or even on social media, mostly I think because they are in similar situations (but minus chronic mental health problems). The second time I woke up tonight due to the "rat in the bed", I fell out and hurt my back. I am seeing a bright camera-like flash every time I blink. My partner came into kidlet's room where I'm now trying to fall asleep to tell me he's concerned as I've had super high sensitivity for a couple days and wonders if I need to call my doctor.
