Always thinking everyone is mad at me

Sometimes I get really upset with my boyfriend and I can’t tell if I’m not having my needs met or if it’s my ROCD questioning things. I can’t express that I’m upset because he rlly doesn’t understand what is going on in my head and most times I bring it up it’s turned into an argument. It is really frustrating does anyone have any tips on deciphering this stuff or dealing with the upset feeling/ bad thoughts (IE: “He’s cheating on me and that’s why he’s not texting.”) (IE: “He’s talking like this because he just doesn’t love me, and he’s not attracted to me. He clearly wants to leave me but doesn’t have the heart to do it yet”)

I'm struggling really hard with relationship obsessions. Do I really love my partner? How can I know? Am I really just faking it? That kind of thing. It's making my life and relationship a lot harder than they need to be. I could use a few helpful coping mechanisms, trying to move away from less helpful ones like chasing reassurance.

TW I’m feeling really bad about myself today. I feel like a fraud and a liar. I’ve been unable to enjoy my time with my girlfriend because I’m bombarded with my thoughts. I’ve been asking for reassurance from so many people and nothing is helping. Nothing makes me feel better anymore and I’m worried that this is just how it’s going to be for forever. I miss when I could just be happy and not overthink so much. I miss being able to get through my days without this crippling anxiety. I’m worried there’s going to be a day where I realize I have no fight left in me
