Welcome to the forum. It’s important to understand that you don’t really gamble to fill the emptiness. Gambling creates that emptiness in you and then temporary alleviates the pain and the very feeling of emptiness (it created in the first place) while you gamble.
Also, it doesn’t give you genuine pleasure. It’s an illusion.
Look at me, I’ve been clean for 5 days and I have wisdom coming out of my butt as I walk.
Anyway, before you figure it all out you need to, as sad68 said, block all your accounts, ban yourself where you can and limit your access to money.
And come here, read and post.
