Welcome to the forum, Becca_59. Menopause is an added complication for women, whether diagnosed before, during or after. Cutting slack is a good approach, but also worth asking to be referred to a menopause clinic if treatment offered by your GP doesn't work adequately for you.
Hope you don't rely on HGV / PSV / minibus driving licence, prefessional SCUBA diving qualifications etc for your job, as that can throw your career completely - it made my BSc Marine Biology gained in my later 20s, just before diagnosis aged 30, virtually useless. If I'd known, I would have done a different degree. Plus I couldn't rejoin TA, which I'd left to work overseas, which is where type 1 diabetes showed at a SCUBA diving medical.
Carry on swimming 🙂 Perhaps add a challenge such as open water swimming [unless that's what you do every day anyway?] or add cycling & running to be a triathlete? I don't compete in triathons, just mountain running navigation races, orienteering etc, plus a few running / biking navigation races, but do marshal at lots of triathlons, mountain races, dirt runs, Blacklight Runs etc, and there are 2 marshals at Just Racing UK with type 1 diabetes - the other does triathlons.
