Lesbian panic chat

So a past coworker added me on HER. Any advice?? I’m lesbian. I know her from a professional setting multiple years ago (pre pandemic). I went through my list of friends to try and get advice and I wasn’t comfortable telling any of them about it. I’d honestly given up on the apps. I just kept my profile open and happened to check it recently. I added her back. And sent a short, nice, open ended question message. Now I’m soooo nervous! I’m such a shy person. But when I knew her from work she was nice. I didn’t know her too good. And we haven’t even had much contact with the exception of 1x bumping into each other just in passing, said hi, then we moved on and had no other contact since she found me online. ANYONE ELSE WITH A SIMILAR EXPERIENCE?
