Depression or anxiety become serious mental burden in the midst of my first move.

I'm just looking for some support, I think it might help me concentrate.
I am 21 and moving out on my own for the first time in one week.
My mum (who I have been living with) is worried about me being able to manage myself because I have been coping with an unidentified learning/depression/anxiety disorder for the entirety of my adolescent-to-adult life.
I will get help. However, I have seven days to finish getting ready for the move and need to pull myself together before then.
Thought mum was worrying in excess but I have spent the last month of my free prep-time anxiously overeating, over sleeping, surfing the net aimlessly and submitting to some awkward manic behaviors just to pass the time.
There is procrastination, but this feels like a downward spiral. Past three weeks I have only managed to shower twice, for example. It stinks - literally.
Just need a push from a real person I think, perusing these psych. and motivational websites without personal feedback doesn't seem to be helping at all.

maybe leaving the nest is just what you need. Just bear in mind also that you haven't seen a doc yet and one visit maychange to whole picture too. Meantime you must not let yourself go to pieces when you have alternatives out there waiting for you.

Moving out and leaving your family (mum) for the fist time can be scary. Have you begun packing up your stuff? Sometimes starting that and getting rid of old clutter can be very healing and motivating. I'm concerned about the unidentified disorders and hope you can find some answers and support with it. Take a shower and do some small act that moves you in the direction you want to go in. Is there something in particular, that you can identify, that holds you back? Make sure when you move you take it slow and stay connected to your mum or other social support.

Thanks oldie, others have suggested the same. My Profs and colleagues have suggested clinical evaluation since as early as I can remember, but I was a stubborn student and am now basically unmotivated. I appreciate the reality check, and will bear in mind.

iNotKraZY: It is scary, especially when evidence consistently suggests I cannot rely on even myself. I have begun packing; it’s just a matter of booking a moving truck (need to find a service kosher with a 4-day heads up at this point, yikes) and getting my funds together. I hope you are right about the healing process. There are certainly identifiable factors that are making me extremely nervous about the notion of leaving, and I have addressed some of these with my family, but there are others I’m afraid I need to “let go” of, lest there be some kind of immediate cataclysmic fallout prior to my departure from the household. It’s been tough, but this is exactly the thing; rather than have some kind of explosive tantrum I just tend to sink into a mopey stasis for unacceptably long periods of time.
I’ve also had a recent, quiet fallout with my social group, whom have been my only strong support system besides my Mum for the better half of a decade. But I will stay connected with my family as much as possible.
Thanks. Here’s to small steps.
