Feel so alone..

I am 5 weeks postpartum and I have not had a break since birth, my birth was very traumatic and i had an episiotomy and forceps delivery. I have not healed properly at all, the doctor stitched me up way too quick, and now i'm left with a wrecked vagina. My son has reflux and colic and has recently caught the cold off me, so things have been very difficult. Esecially cause i'm ill myself, constantly crying and won't sleep at night at all. I am mentally and physically drained, i am living on 3 hours of sleep a night if i'm lucky. My partner works all day so it's just me and my son, it doesn't help that due to the stress and lack of sleep, me and ny partner are like cat and dog the now, argueing all the time and some hirtful things have been said. I feel he is adding to my stress, i feel if he was out the picture that it would relieve me of some stress but also that it could make things more difficult for me. I honestly don't know what to do😳😭
