Hi rebel2
How old are you and have you any idea where in menopause you are ( difficult without a bleed)? Wherever you are, 1 mg tablet HRT is a low dose (perhpas suitable for early peri-menopause) and depending on your age and stage your oestrogen levels could well be falling overall especially if you've been taking it for 3 years. The great Prof Studd has done research on reproductive depression and suggests that some women need much higher doses of oestrogen than the average across the menstrual cycle - in order to feel well. Not suggesting you are depressed but I wonder if you have thought of increasing the dose - either to the 2 mg dose or perhaps switch to transdermal oestrogen - as a patch or gel? Is this something you can discuss with your doctor?
Because it is such a low dose I would suggest it is better to try this (an increased oestrogen dose) before thinking about ADs. How are your flushes and sweats anyway?
As well as increasing your oestrogen dose, there are also various ways of dealing with anxiety other than medication such as ADs which you seem reluctant to take, and especially are not appropriate for menopausal anxiety in the absence of any particular reason for it (personal, financial etc). I'm sure you've thought of all of these and perhaps tried other strategies - is it you that takes a lot of exercise already? Sorry I can't remember everyone's story!
Hopefully you will find a solution soon to enable you to feel better
