As others have said, it sounds like you have an underlying problem. Therapy helps if you do the things your therapist suggests.

The bottom line to remember is that video games like FFXIV are not forever (though since FFXI has not shut down at this point and has been going strong for 16 years, who knows?). Point being--in the grand scheme of things, it's not worth losing the rest of your life and livelihood over something that is temporal, even if you do enjoy it.

As the saying goes, "Moderation is best in all things."
