I also feel like I've spent my whole life using and stuck in the "obsession"...And it is incredibly difficult to know what is...healthy. I feel like every move or make or thing I think I ask myself, "is this healthy? is this what healthy people do/think".
I feel like a completely different person right now, and while refreshing at times it's very scary. Therapy and counseling have helped me a lot. It's hard but talking about it does get easier. It brings things up, but letting it out and getting advice from a professional is amazing.
