Re: How did you get over the ALS fear?
Medication is magic when it comes to OCD. I don't typically overly recommend medication for people who may just be going through an anxious or depressive bout unless it's severe, but it seems for people who have obsessive tendencies or act compulsively and really can't stop, it's a life saver.
Medication helped me immensely the first time I went through a hypo bout with this specific fear, and I just got back on it again because OCD came back with a vengeance (both in the hypo sense and in the sense that I couldn't let people touch the palm of my hands, and I was washing them raw and paranoid to eat food).
I hope the medication continues to help you, it definitely puts reason into our heads. Let's logic win out over emotions.
