hey sahara, the horrible thing about anxiety is that it can come back and attack us at any time. just when we think we can walk with out looking over our shoulder for it, it pounces. then we end up flat, face-first on the ground and wondering how we got there.
i think you're just not back on your feet, you'll get there, but i think you're feeling a mix of dissapointment with yourself and your parents.
i wish i could change your situation. you'll eventually get back on your feet, go out and get your mind off things and let yourself heal. you've not regressed. i don't think anxiety ever leaves us. plus you've probably been under alot of stress lately, go easy on yourself.
