Just need to rant

So earlier in the week my boyfriend's grandmother had heart surgery. He's been staying with her at the hospital so we haven't really talked much. Tonight for whatever reason I just have this small feeling that things aren't going well with her recovery. She wasn't in the best health before the surgery apart from the unexpected cardiac issue. I mean good enough for surgery but not the best for her age. Well, not only that but I haven't talked to him all day. Usually we don't because of his job and I work nights so I'm usually asleep but idk. I've cried three times in the past six hours. About various things such as people not answering the phone, a tv show, and an online video, i think? I just cannot hold myself together. I want to cry again now just typing this. I'm not this sad of a person. Idk what's wrong. 😭😭
