My sOn has severe OCD. He is severely stressed by many things. Right now he is overwhelmed with distress because he feels he may have unintentionally swallowed denatured alcohol, from being exposed to haispray being put on someone else s hair. He believes that the odour he smelled was vaporized denatured alcohol, which he breathed in and which then may have condensed back to liquid denatured alcohol once it came in contact with his nasal passages. He involuntarily had a swallow reflex, and therefore believes he has swallowed this denatured alcohol. He acknowledges the amount is minute but that does not resolve his concern. This is causing such an extreme distress for him that he is expressing disinterest in living anymore. However, he is not overtly stating intent to kill himself. I am looking for information that will de-escalate this for him. Can you help?
