Anyone who tells you that only weak people explore their emotions is someone who has been taught to fear their own emotions above all.
If you go to those bad places in your mind, you have to deal with things. If you think about the trauma & abuse other people (especially family) put you through, then you have to deal with what it means for having them in your life in the present day.
Doing emotional work is fucking painful & scary, but it's necessary for your freedom.
