What grinds my gears? My body. Let me explain.

When I was 7 I started playing tennis. I am now 18 and very, very broken. From the top down things that hurt or aren't doing what they should are my: neck, both shoulders, wrists, all of my back, my hips, my right knee, my left ankle.
[Optional additional reading]Start with the easy bits. My wrists crack like hell and hurt most of the time, no doubt this is due to the 11 years of tennis. I went over on my ankle a couple of years back playing basketball and it has hurt ever since - I've tried strengthening it but when I do, it hurts too much so I gave up and now just wear a big ass ankle brace when I do any sport. I hurt my knee at work and apparently it's my cartilage that's done, this is to be confirmed at the hospital in a couple of weeks but it's not feeling promising.
As for the other stuff... My legs are different lengths, which has thrown out my hips which has made them pretty sore most of the time. This in turn probably started off my dodgy back as it was my lower back that started to hurt first. As tennis involves a lot of twisting and bending I doubt that helped at all... Onto my neck - no idea how it got this bad but I'll blame tennis again. Saw a physio about it yesterday who said it's in horrendous shape. All the muscles are really tight on the left side, including my trapezius which is unfortunate as the trapezius is massively linked with the shoulder and it continues down a lot of your upper back. This is the reason my left shoulder is really tight, hunched up and fairly sore all the time and it's the reason for why my upper back is ruined. The upper back pain and the lower back pain meet in the middle to create my back of horror. [/optional additional reading]
My back is slowly getting better with the massages I'm getting. Knee will be like this for ages. Can't see my ankle improving without a lot of work from me. Neck could potentially be improved by my massages. I've got painkillers for my knee from the doctor but they only work for an hour and a half then I can't take them for another 3 and a half hours so they're next to useless.
I'm just sick of being in constant pain. I can't remember the last time I didn't have pain. I was coping with the whole back pain deal but doing my knee in has tipped me over the edge. I used to still be able to go running, still play tennis, everything but it just hurt a bit. Now exercise has been taken away from me completely - even cycling and swimming hurt a fair amount - and I'm close to snapping. In the last month or 2 I've gained the first weight since I stopped growing (could be a good thing as I'm a skinny wee 🤬 but it's still not making me feel much better!).
The only thing stopping me from having a complete meltdown are a pretty good group of mates + a girl, some retail therapy and the music I love. I'm very close to being in a dark, dark place mentally but thankfully the aforementioned stuff is keeping me happy for the most part. 👍
Sorry about that, but I'm a bit gone after hearing how bad my neck is so I needed to vent. This seemed like the place to do it.
Tl;dr : Body very broken, close to not being very happy, saved from Emoism by stuff.
Cheers for reading if you did.
