I honestly have no idea what hbwr is but my theory about psychs is that state of mind is key. If you think you're going to have a bad trip, you almost definitely will. If you think you're going to have a good trip, you most likely will (barring something to kill the vibe). You also have to be honest with yourself about where you are in your head, you can't trick yourself into not being anxious. The best advice I can give anyone thinking about doing a psych is to wait until you are positive that you are mentally in a place to handle it.
