It sounds like you were creating a scenario by the things you said to yourself in order to bring about feelings that I suspect are very familiar to you: feeling abandoned, betrayed or whatever your exact feelings were. These kind of self-created situations tend to come from childhood experiences.

I don't see where your friends did anything out of line. More to the point, I think it is very important for you to develop awareness around reacting based solely on the stories you decide to tell yourself.

Your resultant reaction will tend to push friends away and then you will feel even more abandoned or unimportant, etc. Next time you can choose to ask your friends where they went before accusing them of any wrong doing. Also, realize that your choice to hide was not based on reality and you might ask yourself on a deep level why you did this so that you can begin to heal the underlying cause.
