I think I have autism should I break up with my fiance M26 Fiance M27

Everything I've been successful with feels like a fluke and I keep waiting to wake up to realize our relationship is the same. University was hard for me but I somehow got a 3.9GPA, my job is hard for me but the clients like me a lot, but I struggle to relate to people. For example the family members of my patients think I'm kinda weird, and I really have to put in a lot of effort for my coworkers so they know I'm an ally (and then reassure them that it's authentic!). I often worry that eventually I won;'t be able to maintain my functionality (it has happened before many years ago), and don;t want to put him through that.
