Hey @Sunnyside226, it sounds like you're having a rough day! I'm sorry to hear that!
Sometimes, it is good to let our emotions out, so long as we do not harm ourselves or others.
I wonder if you could pick something from the following list, like give yourself time to play or scream into a pillow:
Alternate Rebellion | DBT Self Help
Could you join your other child in whatever activity they are engaging in? Or do you need to self-regulate first? Here with you!
You're not worthless! Just going through tough times, by the sounds of it! I know when I am having a bad day, those feelings of low self-worth creep in, but that doesn't mean they are true! You can get through this ❤️
