I have to attempt something really stressful and nerve wrecking tomorrow evening. My future and my family's future depends on everything going smoothly, but for the most part it's out of my control. I know I'm being very vague but it's a touchy and private subject and I don't want to give out too much information. Anyway, I'm 21 and have pretty much no experience with things like this, so I'm ridiculously nervous and scared. I haven't slept all night and I keep getting burst of panic throughout the day. I have no idea how I'm going to prepare myself to do this in just over 24 hours. I feel like I'm responsible for everyone else in my family, which is just too much to deal with right now. Can anyone give me any advice about how to calm myself down a bit? If you've been in these "do or die" situations, how did you deal with it? I've obviously been in regular nerve wrecking situations (work evaluations, exams, the lsat, etc--the usual things), but never anything like this. At this rate, I think I might just pass out when the time actually comes. If anyone can give me any advice I would really appreciate it.
