Do you ever want to just drive somewhere and park up for a couple of hours just to be alone?

I’m at breaking point. I had surgery Friday and both me and my little one have had the flu since Sunday. Last night he was throwing up from 10pm - 3am and back up for the day at 6am. I had to strip his bed and clothes 5 times and I was panicking in case I ran out of clean sleepbags and fitted sheets! I ended up bringing him into bed with me at 3 and sleeping upright with him. It breaks my heart seeing him so poorly and I’m only just about coping myself. I left the hospital Friday at 5.30pm. I was doing bath and bedtime by 7pm, up 4 times with him throughout that night and up for the day at 5am Saturday with him. Since then I’ve continued to do absolutely everything. I’m pretty sure my stitches are infected but the hospital have told me to contact my GP but I can’t get an appointment and 111 wouldn’t prescribe antibiotics over the phone! I can’t ask my parents or friends for help because I wouldn’t want them catching our bug. My husband is avoiding the pair of us because he doesn’t want to catch anything. He’s agreed to do bedtime tonight so I can clean the house and shower but all I want to do is get in my car and disappear for a few hours. I know he will have a bloody wobbly if I do this! I had to go out for bits and bobs today, I was actually looking forward to some fresh air but my little one had an absolute meltdown in his pram because he was tired and unwell. I was stood there, sweating my tits off, weak, holding a bunch of shopping and the pram in the other hand. People staring at me wondering why I’m not picking him up and consoling him. Not sure what advice I’m looking for her myself. Just need to vent
