Saw a psych today and he put me on lithium for bipoar/ocd and bpd tendencies. And xanex for anxiety. My gp had put me on klonipin but it makes me so tired. I am terrified of all the stuff I read about xanex! I just took my nightly dose of lithium and took 1/2 xanex to shut my brain down to sleep. Now I'm anxious about it! What if my heart stops!? :( I know its a tiny ammt, but I'm super sensitive to drugs. Just needing some comfort I guess
