I feel like that with my social phobia. Who would I be without it?
When I get this feeling I try to remind myself that it's only scary from where I stand now. Once recovered I would certainly be different, but in a better way. Besides, I would suffer less. So in the end, it will be worth it.
I know relapsing to your old habits is tempting. It's not healthy, though. And it certainly won't help you in any way. It's not the best thing to do, just the easiest one. You know that, right?
Hope this helps... Take care
