Knee jerk permanent solutions to temporary situations isn't the best way, friend. Maybe it's not just you, maybe it is but you know what you need to work on-and you can with time. People, places, situations come and go. They all teach and reflect truth back to us. Sometimes really painfully. I'm sorry you're hurting but I hope that they're growing pains.
I'm wishing you peace, friend.
Only recommendation is to learn to say what you feel and think in a non aggressive mannor-even if it's scary. These resentments will never go away unless they're confronted. If you never confront them because you're scared to be wrong and hurt someone-they will never know how you're hurting or why there are so many walls up
