My anxiety makes me too anxious to get help

Aw

Basically the title. I’m a really anxious person, more so socially anxious. I have a doctors appointment on Thursday about something totally unrelated which I’m obviously panicking about as usual for me. I want to bring up how I’m feeling but I’m too anxious to talk about it. I’ve tried to talk to my partner about it but he doesn’t understand and thinks it’s silly. We were just at the cinema tonight and I started having a mild panic attack, my heart was racing i felt that I couldn’t breathe and that I was going to die. I managed to calm myself down and stay for the movie. At the end I told him and he was like “well looks like we can’t go to the cinema again if that’s the case” he apologised a minute afterwards because he knew it was insensitive and I can’t expect him to understand something that he has never had to deal with before but I wish he could understand. Also if I go out myself sometimes I start to feel faint and in my subconscious I end up thinking “if I don’t get home I’m going to faint, I need to make my way back” and as soon as I’m home I’m completely back to normal. I feel stupid. Like what can the doctors do? Send me to someone to talk about it and i’ll be too anxious to go and talk to a stranger. I can’t see me “getting over this” and I don’t like the idea of medication either. Idk this is just a rant I guess
