It must be really challenging to have such strong emotions that you feel like you can't control. Do you have any way of relieving the intensity of these emotions, like listening to music or journaling? It's important to remember, though, that these feelings are okay. If they become too intense, you can always try one of the strategies I mentioned before, or any other that you might find to be helpful.
Here at teen line, we're trained to listen to you and help you out with whatever it is you're going through. Our number is 800-TLC-TEEN or 310-855-HOPE
