Charlotta,
whew, what a day. what a lot of things on your mind, with your best friend doing something so detrimental to his health. That in itself would be enough to make me worry no end. Crack, for petes sake, pretty deadly stuff. It would be hard to put worry out of your mind, to detach.
If you;ve never taken Claratin, it can make you feel a little different. I have had anxiety, and on top of that, adding a bit of altered state, it would make it worse, for me.
That lady must have made you feel like you were in the Twilight Zone. ugh. Glad you had options there.
I guess your only option with your bf is to detach, which really stinks. I am sorry, but I bet the anxiety might have been a bit chemical, and it will pass. But your anxiety over worrying for your friend, its understandable. try to remember you can only take care of you, and you must. I do hope your friend comes to his senses soon.
hugs
chicory
