Why do I feel like crying but I physically can’t?

For 3 days I had a feeling that came up pretty often and I cant name it, I dont know what is it and the more i try to see what is it the more i feel worse. Usually letting feeling be and letting yourself experience it helps but not with this. I find myself feel grumpier, triggered and more angry. Its a mix of fear, but then i get angry too and I dont find letting myself experience it helpful cause I just stuck there. It feels like its in my chest and when it gets triggered it makes things hard to enjoy. I tried to be kind with myself and see what causes it but trying to be kind with myself triggers this annoying feeling and it just gets worse... i dont know what helps thats why i ask your help, if you ever experienced this... also i what i almlst forgot to mention, what is really important is that i became really sensitive to every thought, and any thought can trigger this feeling or any thought can trigger a negative feeling that will trigger this feeling. And honestly the "just accept it and let yourself feel what you feel" doesnt helps here cause i find myself really angry that i have to let myself feel the emotions that are triggered by these intrusive thoughts...

My boyfriend just poured his heart out to me. He told me how much pain he’s in — how disconnected he feels from me, how hurt he is that we’re not intimate, that I don’t react to his love, that we don’t feel like a couple anymore. He said things that should’ve broken my heart… but I felt nothing. Nothing. And now I’m terrified. Not just scared — destroyed by the thought that maybe I really don’t love him, and I’ve just been lying to myself this entire time. I keep thinking: “If I loved him, wouldn’t I feel something?” “Why didn’t I cry? Why didn’t I reach for him? Why didn’t I say ‘I’m sorry’?” “What kind of person listens to someone they care about and feels absolutely nothing?” I feel like I’ve been fighting this for so long — like I’ve spent months, maybe even years, battling the same thoughts over and over again: “You don’t love him.” “You’re just used to him.” “You want to want him — but you don’t.” And what makes it worse is that everyone around me says the same thing: “Maybe you’re forcing it.” “You can’t control how you feel.” “If you’re this confused, that means something.” But what no one seems to understand is that I’ve tried so hard. I didn’t want this. I didn’t choose to become cold. I didn’t choose to stop feeling things. I didn’t want to lose my ability to love — or to connect — or to just exist next to him without questioning every single breath I take. I feel like I’ve become someone else. Someone who doesn’t react. Someone who doesn’t smile when he’s kind. Someone who doesn’t feel warmth when he says “I love you.” But this isn’t who I was. There was a time when I loved hearing his voice. When I looked forward to seeing him. When I felt. And now… nothing. Just this endless cycle of doubt, guilt, numbness, fear, and the horrible thought: “If it feels this real, maybe it is.” I don’t know what this is anymore. I feel like I’m hurting him. And I feel like I’m losing myself, too. And the most terrifying part? I don’t feel anything about that either. But if I truly didn’t care — why does this hurt so much? If anyone else has ever felt like this… please, please tell me I’m not alone. I don’t want this to be the truth. I don’t want to lose him. But I also don’t want to keep living like this.

I had the biggest emotional breakdown of my life. I don't even understand why, but because of something that bothered me the slightest bit, i started yelling SOO loudly and bad at my parents: "YOU DON'T CARE ABOUT ME!" I threw some things, i even ran, tried to leave the house, and i ran to my room, i hit my head and i got a bump and some really bad scratches. Afterwards i felt super guilty, i feel horrible for having made my parents feel this way, and how was it possible that I hurt myself like this? I don't understand why i reacted that way, it's so, soo bad. They hugged me and we cried for a while, but i don't understand, am i crazy?
