Okay bit of a rough topic but I need help

There’s not really a rule book to follow for this stuff. I know it’s just what ever works for you.

My fwb im trying to end soon. It’s been the most toxic relationship I’ve ever had my entire life. It’s fucked me up a bit.

I’m trying to meet w this new guy (without the fwb finding out) and he seems nice just quite so I’m nervous to meet with him.

I have a lot of anxiety these days and I overthink a lot. So basically I’ve been sexually assault a lot and raped once. That type of stuff w this fwb.

I’m not wanting to get help. I’m fine. I just don’t really know how to go about starting a new relationship with a guy. Ik I’m not doing anything casual again.

But when do I bring this up? Because I honestly don’t know how I’m going to react if I do get together w this new guy. I don’t want to be crazy emotional or anything. And i feel like having sex w another guy is going to be hard.

1. Because I’ve only been w my fwb.

2.

I feel like I always have to say yes because Ik that saying no doesn’t work sometimes. And if it does then he might get mad like my fwb does. Or he’ll just keep going anyway.

And like what if I start shaking or freaking out or something ?? The guy might just deem me as crazy or too much to handle.

I mean I have to get into a relationship at some point and Ik I’m ready for one. But it’s just this topic that gets me.
