Ye course you can still do everything as normal. Work and that. You will just be feeling mentally down and depressed. Ive know a few people to commit suicide from it. It makes you feel so sad its awful. And i know what you are thinking.. why get it then? And i think the same.
Its like a little devil on your shoulder telling you.. just get one. You will be fine.. you will get up in the morning and go out with your gf.. but when the next day comes all that has gone out the window, with being on a come down.
