I'm in pretty bad shape. No, I don't mean weight, heh, I mean health, and I'm hoping someone here can give me advice on what to do urgently.

I've been ill for years (I'm 28, 29 on the 4th of this month, and have been ill since I was 17), and the stress is cracking me. I'm not sure what to do next, but it needs to be very soon.

I went to specialists years ago through GP referral, but an endoscopy, colonoscopy, and kidney ultrasound (and a few more of the latter since then) revealed nothing (though the endoscopy said I had an open bladder neck and a hole/weakness in my bladder wall).

I'm incontinent (as in constantly leaking and dripping -- there is no relief. At all.), house-bound and bed-bound a lot of the time, I can't sit down without being in terrible pain (it feels like my rear is collapsing on in itself), have kidney pains (probably from vesicourethral reflux), stiff joints and body areas/numb hands and a constant feeling of sickness, and a black spot permanently in my vision (recent development, with flickers too). Breathing troubles, acid attacks, and coughing fluid often occur.

I've also had complete vision blackouts and fainting spells before, though they're rare.

I know what the root cause is: idiotic self-harm through OCD when I was a teen (personal, I won't go into it).

I honestly believe I have some sort of internal prolapse in my rectum/anus (or perhaps external, as one of the symptoms of that is also present -- something 'sliding out' when flexing/straining), as I match all the symptoms and signs to a T (literally, I can pick them off a check list).

Just poking or touching that area externally causes me pain, discomfort, and an aggravation of symptoms.

I'm in complete misery, and don't know what to do: should I go to a walk-in centre? Though they say they're not for "chronic conditions".

111? Apparently completely useless, and there have been stories about them being more harmful than helpful.

999? Not an immediate life-threatening emergency, like a heart-attack.

Go to a hospital's AE by own means, and not an ambulance?

I'm honestly at a loss here, but I know I* can't* wait weeks and months. I'm going* insane*.

The stress of dealing with this for over a decade is getting to me.

Please: does anyone have any advice?
