While I understand your reticence at taking medication, I would strongly recommend it, it will get you out of the pattern of srutinising yourself in trepidation and help you to think more logically.
Here are some other resources that you may find useful...

They offer help and advice, and are fantastic resources.
Please keep us posted, and thank you for sharing your difficulties. It's a very courageous thing to do, especially online.
All the best,
