your actions were your bodys subconcious way of crying for help. it knows there is something going on that needs sorting out even if you are unaware of it, the Psych ward is the place for this to be identified. once identified many conditions can be successfully treated to a level where you can become a successful valued member of your community.
missing your birthday was not nice i agree, but without this treatment you could have done a lot worse and missed the rest of your life!
you need to be strong, this blip is only a part of you not the whole of you, keep a hold of the things you love about yourself, all the things you are good at and the nice things you do, these will help you re find yourself and give you the confidence to get through this and come out the other end.
take each day one at a time and be gentle with yourself xhugsx
