Dead bedroom due to illness and possible menopause

So I (47 hlm) and my wife (42 llf) have an almost none existent sex life, maybe once every six months for the last 3 years! It's possibly due to her depression but this wasn't a problem in the past (married for almost 20 years), her doctor thinks she could be seeing signs of early menopause, could this be a factor? I'm guessing so! And is there anything that could help? I have a high libido and it's driving me crazy lol!
