Am I crazy or what?

Lately I feel like something has been off with my boyfriend. I feel like he dosen’t really have any interest in talking to me and would rather keep to himself or sleep. I have been worrying myself to death thinking he is losing feelings and is gonna break up with me to the point I’m crying myself to sleep. (I know it is dramatic) I know I should talk with him about it but clearly he will ask why I’m feeling this way and honestly I don’t know. I feel like it is little things like the tone in his voice or just little things he says which I don’t really think is a valid reason for me to feel this way. I feel like I’m acting like a child and being crazy but I get this gut feeling he is about to cut it off with me and idk why. We are about to make 2 years in 2 weeks and I would be torn apart if we broke up. I know this dosen’t really seem to add up or make sense but idk who else to come to.
