Hi sarahy
Sorry to near about your anxiety - but I agree I would resist all attempts to try to put you on anti-depressants when it is likely, as you realise, your problems are hormonal.
The things is - firstly although oestrogen blood tests are not normally carried out - because they are inaccurate and docs should go by symptoms, in your case because you have both symptoms ( anxiety) AND lowish oestrogen levels - then adjusting the HRT would seem to me the first option.
In terms of actual levels - mine have never been 300 pmol/l since taking HRT - though I'm not sure what they are now! Mostly around 200 when they've been measured ( and less than this at patch change time - have since increased dose) - so it is what you feel - and I have always felt well on HRT with min 50 mcg patch.
So you have already been given an increased dose - off licence by presumably using 1.5 Evorel conti patches, which hasn't improved things?
One thing that has not been mentioned is progestogen intolerance. It could be that your anxiety is partly due to the continuous dose of norethisterone - which some women react negatively to, so upping the oestrogen dose of the patch also means an increase in the progestogen. If you are a woman who is sensitive to this progestogen then no wonder you didn't feel better on the increase?
Re: "but investigations have found no cause. So the doctor doesn’t want to up my hormones until the cause is discovered."
Bleeding is also tricky to control if you are on a combi patch - if the doses are not the right balance for you. Can you elaborate on what investigations you have had? You should have had a U/S scan + TVS (vaginal) and if the lining is found to be thickened or has any potential abnormalities, you should be offered a hysteroscopy and possibly biopsy.
I can understand not wanting to increase dose until this has been sorted but this should be pretty quick in the case of post-menopausal abnormal bleeding on HRT?
My view would be to go for separate oestrogen and progestogen and/or cyclical HRT so that you can see which if any progestogen you tolerate best. This would enable you to tweak the oestrogen and progestogen doses safely and separately so that you both feel well and don't have bleeding.
I suggest you read up further about the different types of HRT ( menus on this site), decide what you would like to try, and after the investigations are complete, go to your doc (or a different one in the prctice) with your request (having written down your reasoning to help you remember!).
Hope this helps and ask if you need any further advice!
