That sounds awful, OP. It's such a shitty thing to go through especially when you just want to enjoy that 'newborn bliss' some women seem to experience. It's not easy to look after a baby with all this going on I bet! 
The only tear I could feel was a labial tear and the midwife told me it's the most painful place for a tear due to all of the nerve endings. As it wasn't bleeding in the delivery room they didn't stitch it however it was almost 2 inches wide by 3.5 inches long (meaning I had very wonky flaps). A few days in I was crying to DH that I was never going to recover and was going to have a wonky fadge forever!
The first 2 weeks were absolute hell. I had to pee in a full bath to try and dilute my urine yet I would still be crying in agony every wee despite being dosed up on Paracetamol & Diclofenac (a stronger alternative to ibuprofen I believe?). The midwife kept assuring me I was healing well but I was convinced she was deluded!
After about 10 days I was able to wee in the shower with water running but I was weeing in the shower for almost 3 weeks (every half an hour - bladder problems really did me in there!), along with walking like a penguin and not being able to sit down properly. My little 'routine' was to get in the shower, fully rinse down there after weeing, gently dry myself with a clean flannel each time (I had a basket of 20+) and then get dressed. I wore the mesh knickers from the hospital with a maternity pad just for the cushioning and DH's boxers over the top.
Whenever I went for a number 2 I would wet a flannel with cold water, fold it up and hold it on my vagina & I didn't push at all, I just waited until I was ready to go as I didn't want to strain.
I had so much pressure from friends to leave the house and go do things but I just couldn't bear the pain of walking down my drive, or the thought of being away from the shower in case of a wee! Obviously, none of my friends had experienced childbirth or an obliterated foof.
I remember feeling like life would never move on & the pain would never get better so I really feel for you in a worse situation that I was in! I would say I was completely back to normal by about 6 weeks but was managing to wee normally(ish) & get out every so often by about 4 weeks. I'm also relieved to say that when it healed I was not left with a wonky hoo-ha somehow, and all looks and feels normal down there.
My advice: bother your midwife/maternity unit/GP for diclofenac (when I ran out & used ibuprofen instead I noticed a huge difference. Safe for bf too); get some Spritz for Bits & a portable bidet bottle if you think that would work for you; don't let anyone make you feel pressured; request and accept as much help as possible!
It sounds like delivery was a little traumatic for you so if you need to then please don't feel any shame in asking your midwife or GP for help, even if it's months down the line. I hope you recover well as soon as possible
