I am not understanding what you are trying to do or what you want.

^^ what he said...

Come on kaue-jj, slow down, take a deep breath.
Try to tell us specifically what is happening and what specially you want help with. Breathe. This is no place to be talking about "things", everything has a specific name or term for it. That's we need to figure out your problem

Like everyone said, calm down, first, is the attack over SSH (trying to gain root access using dictionary attack) or are they just overloading your server with web requests.
You say that you have Cloudflare, so, if the attack is on web requests, go to your Cloudfalre account, select your domain, select cloudflare settings and under the security tab there is an option called BASIC PROTECTION LEVEL, change that option to I'M UNDER ATTACK

This will slow down the requests to your web server, if you need something more advanced from cloudflare, then probably you will need to pay for the business plan
