I haven't been able to cry in a really long time. I hate it

For the record, I don't mean I'm being pressured out of it in any way that I just feel like I can't- I just literally, physically haven't been able to. I can have bad day after bad day, ruminating on everything that's ever happened to me...I can get so so sad, but not 1 tear falls

An eye gets wet sometimes- twice a month-ish. Sometimes it actually rolls down my face if I'm lucky

This all sounds like a good thing but it actually really sucks. Crying is an emotional release that I just- physically don't have, for seemingly no good reason. Is something wrong, for this to be the case? If you know why this happens, tell me
