You have a good cry, hormonal fluctuations can affect moods so it's good to 'let go'.

Yes a hysterectomy will help your problems, it is major surgery so you need to discuss exactly what will be done and whether you will need HRT after. Of course without womb you shouldn't require progesterone. Again, take a list along to discuss.
Let us know how you get on. We shouldn't have to get a private appt. but I've done so when necessary, as there will be more time to talk about your problems. Many private consultants work part time for the NHS so U may find that during the appt., he/she tells U that your treatment can continue on the NHS. U shouldn't have to rely on insurance unless surgery is involved.
Do be aware that during private treatment, patients aren't covered by a 24/7 service as we are in the NHS. i.e. if a patient has a heart attack for example, there won't be a crash team on site, the patient may require transfer to an NHS hospital with a bed. I didn't know this when I had my various procedures

. Everything has to be paid for, removal of a single running stitch cost a tenner in 1992. I could have done that myself! So X-rays, bloods, ABs, are charged for in the private sector as individual invoices.
On the Forum is a long list of 'hints for husbands', might be worth you printing it off, reading, then handing it over 2 hour husband. [I found it slightly patronising ...... however.]
