Tip: don't think.
Sorry noob, I don't have any helpful tips... I'm the kind of guy who never stresses about anything. I can't remember the last time I remembered a dream I had... It's been years. Everything that happened has already happened, and everything that will happen will already happen, so there's no point stressing about it. Just face it when it happens. All I could tell you is to think of life like that - but I guess that's easier said than done.
