Social anxiety

Hi there, I’m not sure if I suffer with just anxiety or social anxiety. I’ve always been shy as a child but as I’ve got older I’ve began finding myself dreading social situations and this has obviously worsened through covid as I haven’t seen anyone. I’ve been invited out by friends and I agree and then find myself getting more anxious leading up to it and then cancel the day before. I know that if I went I’d be fine but it’s leading up to it and then after it I know I’d be going through all the conversations I’ve had wondering if I’d said something weird. I also get anxious over little things like asking questions to people like my manager. I end up picking the skin around my fingers to the point I’ve got cuts all around them and i don’t know how to stop doing that. I’m too scared to go and see a doctor about this just because it’s not an emergency and I’m scared the doctor will think I’m being over dramatic. Is it normal to be like this?
