I want to offer something positive to go with that downer -- you can find people you can come to trust enough to talk to honestly. There are many investors who are great people who, once they've decided to back you, are going to be there for you and understand the roller-coaster ride and won't hold it against you. You can find co-founders who are level-headed and have the right expectations, and don't get freaked out by some straight talk. You can and should talk to family members and significant others. That way, it can be 'us against the world' rather than 'me against the world'.
