Everything is going wrong

Hello sir,
When I have started using cloudflare, everything is going wrong. Neither I am able to access my website nor other people are able to access it. And my website doesn’t show IP address also. Nothing is happening good. Neither my site shows SSL or https protected. I don’t know what to do.
Will everything be normal as before if I delete my website from cloudflare and change my name servers?
I am new, I don’t understand anything in cloudflare and no one is helping neither the blogs. So I think I should not use cloudlfare anymore. I am sorry for this, but what can I do?
Please help me this last time with my question.
