Interview Anxieties

Hello.

I'm feeling very anxious over my interview which is tomorrow. It's going to be my first job interview and I'm going crazy thinking about it. I've done a bit of research on how to stay calm and not over think it but that hasn't really worked for me yet, it never does. When I get anxious it's like being a passenger on board an out of control plane doing a nose dive. I've written out some questions that I might be asked during the interview and wrote down what my replies would be.

But then I thought what if these questions aren't even asked, and even if they were, my memory isn't good enough to remember what I answered here and now and I doubt I'll be as confident in person.

That's the problem with me I over think and over analyse everything and I don't know how to stop it. My sister has been kind enough to tell me of her own experience with job interviews and that's helped a bit but she is charming and funny and I am shy and quiet. I have no confidence and I suck at talking to people, I always have since I was able to talk.

What I want most is to come across as me in the interview, honest is the best policy, but not too much me that I'm weird or at worst have a meltdown or go into shutdown. If that happens then I can guarantee the interview will be over and I definitely won't get the job. I don't want to mask and come across as somebody I'm not. I can't mask for the rest of my life every time I go to work. I did this at school, it helped me get through the majority of my schooling life but the negative effects it had on my mental health have hit me hard since school and I'm still trying to deal with that now.

I want so badly for this interview to go well but I have a horrible feeling it's going to go badly.
