PTSD and Long Distance Relationships

So my boyfriend knows I have PTSD but he doesn’t know the story of the trauma(s) that caused it because I don’t wanna tell him until I see him in person. I’m having a really bad day today and every little thing is triggering me. I just wanna tell him, I want cuddles, I want to feel safe, I want someone to talk to. But i can’t because he’s not here. He said he was a little upset (not at me but at the fact he can’t be here as soon as he wants to be because of Covid) but for what ever reason that triggered me a little. I hate it. It’s ridiculous. Him saying he’s upset shouldn’t trigger me. I feel weak. I feel unsteady. I’m jumpy and I hate it. I feel like I’m not being strong enough. Idk it sucks. I just want him here.
