Hello Bluesclues445, when people feel anxious they can say what they normally wouldn't do when feeling OK, the problem is they may be unaware of what's happening.
If these people are what you classify as being friends and have told you that you are 'overreacting', then they may only be saying this regarding this point, but it doesn't mean they aren't your friend anymore because friends get cross with each other every now and then, and the next day it's all forgotten.
If you don't feel as if this is going to happen then you can contact Kids Helpline 1800 55 1800 by phone, web chat or online.
This group helps people aged between 5 to 25 years of age but hope to hear back when you're available.
Geoff.
