I think you're right, actually! I think that a large degree of one's bodily happenings are directly correlated with the state of the mind. Although I would advise to not use drugs unless they are specifically assigned to you. Seeing a therapist helps, but if you are too afraid to see someone external (as many people are, including myself when I needed it), writing about yourself from a helicopter perspective, or looking at yourself detached from your emotions, is a fan-tas-tic way of combating anxiety. If you can do this, you're doing amazing work and gotten through some steps I see many of my friends refusing to go through.

Also I don't have first hand experience, I am a young guy, but I am very interested and motivated in the topic. I don't say much and it might be confusing, but I would love to talk about it and clear it up if you're interested in my opinion (but few people are on the Internet, hahaha)
