I Can't Stop Crying It Literally Feels Like Any Emotion

I can't stop crying it literally feels like any emotion I experience even the good ones have me breaking down. I don't know what to think, my mom mentioned diabetes and I mean I have trouble digesting fibrous foods like lettuce and sesame seeds they come out whole so I'm starting to think it's an actual problem not just me "not having a handle on myself" because I really can't correlate the crying with anything except emotion and a big lump that forms I'm my throat that everyone gets when they cry. What would be maybe a chemical imbalance that causes irrational amounts of crying? It's literally dehydrating me.
