Seeing other people dealing with the same thing you are is a great way to feel less alone, but if you found a lot of things in this post a little too relatable, you might want to look into other ways to take care of yourself. So, here are some quick resources, just in case:
You might want to read more about BFRBs and check out resources and information on how to get treatment.
You can read about anxiety disorders and obsessive-compulsive disorder, since BFRBs can be a symptom or coping mechanism of both.
