omg! You poor thing! Yes! I can relate! I am agorophopic but it has gotten debilating now. I worry all the time I am screwing up and work and about to be fired. Then I get so mad at that "fantasy," I think no one appreciates me and I want to quit. I fixate on these things. Every single bloody (to pick up a phrase from the UK) morning I want to quit my job. And I "LOVE" my job and I am the bread winner too. I fatasize about getting addicted to something and sent off to a recovery center like they do on TV shows (don't know if you get it in UK, but there is a show called, "Intervention" where they capture drug addicts and their families intervene to send them away ((it sounds devine in some ways!)). I WISH someone would put me in the hospital so I could go on disability, but I don't have anythign "wrong" with me. It's just menopuase. "Just" - HA! If women ran the world, we would get porper care, attention and medical intervention (and I don't necessarily mean HRT, but how about if insurance covered Accupuncture - it doesn't in the US).
I, too, was on antidepressants for 17 years and was prescribed them for a catastrophic event in the late 1990's. I probably didn't NEED them then; just some therapy... but I didn't know any better. I desperately do not want to go back on them and this forum is helping me realize I am not crazy - just hormonal. I had ear wooshing or feeling like a pulse was in my ear... and eye pulsing (like a heart-beat in my eye lid).
I had terrible bladder problems but they were bad enough in 2010 for me to get surgery to repair my pelvic floor and I got the bladder "mesh" to pick it back up from sitting on my pelvic floor. I wore "Depends" (adult diapers) because I peed my pants all the time. I don't know if that surgery is an option for you in UK but most insurance covers it. It took that problem away 100%.
I had dizziness and confusion and vertigo too. It was helped by thyroid medication (just a small dose). The thing I learned is that, while my GP kept testing me and saying (a) I wasn't in Peri-menopause and (b) my thryoid and everything else wasin the range of normal, those RANGES are often too broad for everyone. AND our hormones fluctuate daily so even if your estrogen levels blood test "normally" the day you go for your blood draw, does NOT mean they would me normal the next. So, you have to find a doctor that ackonwleges that and will treat based on your symptoms -- using blood tests as a tool -- but not the ONLY tool. For me, that person was a naturopath. Insurance doesn't cover her so I pay cash. She is worth it. but I have to get adjusted a lot. What works one month, does not continue to work each months. Although, what you describe (and I experienced in the summer of last year) DID go away with these interventions:
Armour Thyroid 30 mg (now at 60 mg)
Progest cream (one "pump" - about 1/8 of a teaspoon) nightly
5 drops of Estrogen oil (out of the regular dose of 10 drops)
Calcium
Magnesium
Multivitamins
(I also take Klonipin for anxiety - I take it every night and it helps with panic attacks and pain)
I am going back to have my meds adjusted for the recent sypmtom which is severe muscle and joint pain and crying every day in my car and I have decided to eliminate wheat products because, although I am not allergic, I do notice puffiness when I eat bread, pasta, etc. So, since "Gluten Free" is a big "craze" here in the US (espcially where I life in CA), I'll take advantage of the gluten/wheat free bread and such 
I wish you so much luck and love and hope!!! keep writing and keep us posted!!
