I'm going to ruin two events in a row
Why do you want to ruin two events?
My friends organized the events without me so I want to ruin the events.
It is understandable to be upset when your friends do not include you in their plans, but you should not ruin their events because of this. You should respect what they have done and volunteer to help them.
I feel attention starved I want them to recognize me!
Have you tried talking with them to tell them how you feel? If they are unaware you can't expect them to magically guess what is going on. Don't act like a toddler throwing a tantrum.
