well... depression is wanting to lie in a corner and cut off from the world. not wanting to talk to any one and hating just about everything... even what u love to do most....
the best way to do this is to engage in some mental activity... this is what i find relieving... it gets ur mind off from the depression thought... for e.g. me being a book lover... i get an interesting book and start reading.. even though in the beginning i cannot concentrate... i continue... after a while it becomes engaging and you can feel your self leaving the bad thoughts behind...
apart from that.. you can go on a walk.. talk to someone about your problems and concerns and try to do some cooking.. its a full time job and does not let depression come in between...
i hope it helps you...
