My [24M] girlfriend [23F] has a lower sexdrive because of narcolepsy and a worry that I will leave her and it’s driving me crazy. Should I breakup or keep trying?

I’ve been together with my girlfriend for almost three years and love her a lot. She has a great sense of humor, takes an interest to my hobbies and is a cool person.

About half a year after meeting her sex drive went from wanting to have sex 1-2 a day to maybe 2 times a week. This happened during summer were we where apart and was something that we thought was just a decrease that might happen in a relationship. A couple months later she was diagnosed with ”light” Narcolepsy which basically means she doesn’t fall asleep during the day but that she gets no help from her body in feeling awake. This meant that the her having the energy to work out stopped and we have both stopped going to the gym. This meant a further decrease in sex drive where it was more like once a week.

Half a year ago I decided to go on an exchange. A couple weeks before going I feelt really bad about the lack of sex and generally about how much energy the relationship takes. I decided that the best course of action was to break up but was scared as hell since I live her very much and didn’t want to lose her. I therefore talked with her and said that I fell like we have to break up and asked her to please tell me how we can fix this. Because of the way I phrased it she now feels that we are only together because of her arguments and her trust in that I’m not going to leave her is very low. Somehow we managed the long distance quite well even though it was rough for her but I tried to support her by facetimeing almost every evening.

Now when I’ve gotten back however the low sex drive has gotten even worse since she has also had an increase in the amount of anxiety she has. I’m doing most of the house work and getting very sexually frustrated by this situation. At the same time we have had very productive talks on the matter and she is very mature in recognizing how important sex is for a relationship but also clear in that she is going to need a bit more time to get her trust back in me.

I feel like I’m at the end of the rope in how much energy this relationship is taking from me but at the same time she makes me laugh and gives me purpose. I don’t know what to do and am desperate for advice.

P.s. this is a throwaway and english is not my first language so sorry for any spelling mistakes!

TLDR: My girlfriend is a wonderful person and I love her a lot but the amount of energy the relationship takes and the sexual frustration I’m getting is driving me insane.
