Hormonal turmoil at menopause saps your confidence which, in turn, means you can't deal with things in the same way. Then you lose even more confidence and things become a real struggle. the two things most affected seem to be work and social events.
I don't know what the answer is but I know that avoiding events doesn't help as you gradually get isolated. I have found that being honest about how I feel helps to offset things and tells people that I am not able to manage as well as I once did just at the moment. If they don't like it then that is their problem, not mine. Most people seem to understand or try to anyway.
