I can relate to this too, SoScorpio. It can happen to anyone. I did go on wrong bus once too and have had other incidents similar like you have had.

In these days I write down on paper what I have to do and remember in case I forget it. Its easy to forget when our minds are troubled with stress, depression or anxiety or a mix of them all. Smoking pot makes it worse so it may be a good thing to stop the Mj.

Dont be to hard on yourself.
