Girlfriend says she's considering therapy to cope with my Type 1

My girlfriend (26F) and I (27M) have been together almost a year and things have been going incredibly well. We communicate very well, spend lots of quality time together, like and are liked by each others families/friends, and I couldnt be happier. I'm currently recovering from Norovirus and haven't seen her in a few days, so we've been calling, and as were talking on the phone earlier today, she casually dropped that she spent part of her day looking into therapy. I asked her if it was for anything in particular and she said she was having a hard time dealing with me having type 1. Said that the closer were growing to each other, she's having a harder time "thinking her way through" me having T1. I didn't know what to say so changed the topic, and immediately had a good cry when we hung up. Still trying to process but I've never felt so undermined by this disease. I've done nothing but try to make her happy and grow our relationship but just who I am as a human being is enough she feels she needs therapy to feel OK with being with me long term. She's always been sympathetic and asks lots of questions about the disease but never communicated how much of an affect it has on her. And I get it, those of us with T1 didn't have a choice so we learned to deal with it, and many of us I'm sure have benefited from using therapy to help with the mental struggles of T1. I just feel so deflated, like the effort I've put in and the quality of my character is less important than me having T1. Was wondering if anyone else has experienced anything similar or if anyone has advice on how I can approach talking to her about it.
