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

I feel really anxious since i decided that i will go get a blood test. Today i went to get a haircut and the whole time i felt like i will faint, vomit, i dont feel good and it was horrible. I came home and started to read about how to deal with emotions. I found a really good article, and I started doing the work. I thought that im avoiding my emotions and I dont now what i actually feel so I went inside and after some time a thought and a feeling came up that said "i wish i could tell this to someone who would listen to me and nurture me" and i felt so good thinking about this. But then I started thinking maybe i should go to therapy cause noone will listen me here, and i started to feel sad and it got worse and worse. Its been hours now and my mind keeps thinking about "noone listens to me" and it keeps me feeling sad and depressed. This is is why i dont like to think about my emotions. Now I dont know should i act on this strong emotion, should i run and talk to someone? That feels like a compulsion. I felt this before,alot of times when i struggle i feel like i wish i could tell this to someone, and alot of times i do,but i dont get the reaction what i want. I dont like that we should act on every deep feelings we feel. If i feel this than the only answer to heal this feeling is to run to somebody and talk about my feelings. I dont like it that now nonstop i feel this and think about this and i cant move on.

And what is happening...let's say I come across a video of that person and then I stop the part where it triggers me and I deliberately imagine images of a sexual type, and if I don't feel anything, I look again, as if I want it or I have the urge to imagine it, i.e. I feel the need, and if I feel something or get a feeling in my groin and I feel like I fall into despair?

I’m really struggling and I feel emotionally drained. Every time I spend time with my boyfriend — even when we do something nice, like watching old videos or just being together — I feel this heavy, painful disconnect. I keep having thoughts like “I don’t like him,” “he’s annoying,” “I feel nothing,” and it feels so real. We’ve been together for 2 years, and this has been going on for more than a year. It’s exhausting. I feel like I’m constantly chasing a feeling that never comes. I’ve read everything about ROCD, about ERP, about how I’m supposed to sit with the thoughts… but even when I try, nothing makes me feel better. I can’t tell what’s real and what’s not anymore. When he wants to see me or come over, I avoid it. I don’t feel excited. I even feel afraid of being around him sometimes because I’m scared I won’t feel anything and that confirms my worst fear: that I’ve lost feelings or never had them. My chest feels tight all the time. I feel like I’m lying to myself and to him. I know he loves me so much — he even moved to my city to be with me. And yet here I am, thinking these horrible thoughts and feeling nothing. It makes me feel like a terrible person. But I’m also just so lost. Has anyone been through this? Where it all just feels too real, like you’ve hit the truth you’ve been avoiding? I feel like I’ve ruined everything, like I’ve been forcing feelings all along, and now there’s nothing left to feel.
