Help I’m really struggling

So I’ve had really bad anxiety all my life it wasn’t too bad before I graduated high school now I’m still trying to get my license, going to college struggling with getting a secure stable job. My parents are having issues and my mom hasn’t been home for the last month and she’s depressed, my dad is getting by but he relied on me a lot for emotional support and advice. My cousin died from me Pneumonia, and my anxiety has shot through the roof. I’m in a long distance relationship and wonderful guy, we love each other mutually but things have been rough between us. He called me telling me he’s been depressed, and he feels like it’s hard to talk to me. Which is understandable, I have ADHD and anxiety and I’ve been constantly thinking, can’t feel like I can relax and I want to be someone he can talk to I love him so much. So I’m going to therapy to work on my anxiety and to really learn to quiet the constant thinking for myself and to be able to be a better listener. I didn’t realize how much all this has effected me and I so scared. I’m so scared of failure. I’m scared of saying the wrong things, I’m scared of not having words to say. However the phone call with both of us saying I love you. Nothing has been said about breaking up. I’m trying best but it’s hard. I feel bad that I’m not the best listener, because that’s all he was asking of me. And I can’t even do that. And it feels awful. Any kind of advice would be amazing. And much appreciated.
