Overreacting?

I recently had an aunt pass away and I didn't think it'd hit me as hard as it would since I wasn't very close with her, but it is. I told my SO and at first said I was fine but then later on the day after seeing my family it's just gotten harder. I was a bit snappy to him yesterday since I was just so tired and also pissed off bc some bitch scammed my cousin $500 and I said something too bluntly and apologized right after it, we spoke a bit and then we said our goodnight as always.

Today I asked him if he could stay the night since my family will be gone and I didn't want to be alone. Now can't come Bc he's with his mates. The whole entire day he has just been so blunt with me and I honestly dont need this shit right now and just want to cry about it... not sure if I have a right to be upset and I know I should just ask him what's wrong but I'm more pissed off with the fact he's acting like this when he knows I already feel like shit.
