Applied at Staples for Unknown

I have my first job interview this week at Staples, and I’m feeling really nervous about it. It’s been a year since I graduated college with a major in communications and minors in studio art and art history, and I’ve been putting off applying for jobs because I’m anxious about the whole process. I did have a brief stint as a retail associate at Goodwill through a program for people with disabilities back in 2019, but I didn’t have to go through an interview for that role. Now, after six years, I finally decided to apply for a few jobs, and tomorrow is the big day. I’m really worried about messing up during the interview because I have ADHD and social anxiety. I struggle with eye contact and sometimes take a bit longer to respond, which makes me fear that I’ll come off as unprepared or disrespectful. I’ve done my homework on the company, noted down their values, and even laid out my clothes for the interview, but I still can’t shake the feeling of panic. I’m reaching out to see if anyone has tips for staying calm and regulated before and during the interview. I’ve read some strategies before, but I’m unsure if they’ll work for me. Also, should I consider disclosing my disability during the interview? Any advice would be greatly appreciated.
