The situation is clearly impacting you negatively and rightly so. Unfortunately it's likely that you're affected by the consequences of her being deeply affected by what she's been through so in the end it may have very little to do with you.

If she's had a hysterectomy and clearly has gone through some serious health scares, you have to keep in mind that she's probably going through a very life changing, traumatic experience and that can make people act in ways that aren't perhaps easy to deal with, such as repression, depression, withdrawal, anger, etc. She might be in the stages where emotionally it's hard for her to provide much, a stage where she needs more help and support and can't offer much in return whether she wants to or not.

Hormones do influence our emotions and desires but not to the extent where without hormones there's no emotions or physical needs. Everything from cuddling to sex is primarily about connection, intimacy, not being alone, need for touch, validation, love. Those are needs people have regardless. The lack of hormones probably affects sex drive but there's more than that, there's that emotional part, the trauma of having a hysterectomy and having been ill.

Only you can decide if it's a deal breaker that maybe for a while, longer or shorter, she won't be able to have sex or offer much in those terms. As long as you've been good and truly patient and stuff, this is not a question of you turning her on or not, I think this is a question of getting over what happened to her and adjusting to the situation.

You have to seriously think if you want to and if you can handle being with someone who might not be able to provide much for the time being, someone who needs more than she can give perhaps and who might be frustrating at times. Everyone is worthy of being given kindness, support and patience when something life altering/mentally altering has happened to them but not everyone can provide that without becoming bitter or depressed themselves. How was she before? What was her way of being? Those are all things u should take into consideration.
