anxiety does weird things to me. exhausts me. escalates me to the point I feel like I am going to go over the edge. and that is just an ordinary day. im anxious for no reason. I can say I ever gotten fogged up, but maybe. theres many times I haven't been able to think straight. often times I have hallucinated as a result of my anxiety. mine is linked to my ptsd as well. I take buspar to keep the edge off. that has kept the hallucinations at bay. I have klonopin for when it escalate. I just live in a constant state of tense. I wish I had more to offer you. just know your not alone.
