Aw Sophie, I'm so sorry to hear how you're feeling, but please forgive yourself for taking the Clonazepam, no one can know how truly awful it is getting off of them without actually going through it.
Being warned by your doctor its addictive means nothing to people like you who aren't addicts, who take the medicine as prescribed and don't abuse it. You know yourself, you knew you weren't an addict so you bought the drug in Mexico because you don't fear addiction and took it judiciously. Please don't add to your distress by being angry with yourself.
What you're feeling is so common, its difficult to be around people and the stress of having to fake it around company is probably exacerbating your symptoms, stress can actually make us feel worse. I hope you can carve out sometime for yourself while they're here to recharge.
I know what you mean about the smoke, it's so oppressive, hopefully the weather pattern will change and bring you some relief. I hope the massage helps you feel better.
