Frustrated and slowly approaching my last straw...

Im the one with ADHD in the relationship. Or the one that has been diagnosed anyway. Im writing here because I have nowhere else to turn without being judged. I'm tired of wanting to say something and not doing it out of fear of starting an argument. If there is one thing I just cannot handle in this world, its my loved ones not speaking to me and being angry at me. For example tonight my bf gets home from work and asks me what I did today. I answered with my usual daily chores along with jokingly saying I wanted to cut my foot off (I recently was bit by a fire ant and my foot has been itching REALLY BAD all day long). Then he responded with I'm glad you didnt. Then I asked him what if I didn't have any legs, arms what if I was blind, bald etc. He answered with his usual funny joking answers, but thats not what I was after. I wanted to know if he would still love me, think of me as being attractive, and still want to be with me if I was any of those things. He wasn't getting the point (or so it seemed), so I told him if he didnt have any arms or legs or was in a wheelchair, I would still be here and loving him as much as I do now. I wanted clarification. Every girl wants clarification every now and then. Why is it impossible for men to understand that?! I wanted to keep pursuing. But I knew if I did, we'd be in a different situation right now. I'm so tired of feeling like I can't talk to him about something that is bothering me without causing a fight. I don't know what to do. Frustrated Floridian
