Oh, and Mark, if your still reading the chat I had a question that maybe you could answer, as you seem pretty knowledgeable on the topic.

So I am trying to treat my anxiety through weight lifting, because I'm hesitant about taking medication, and excercise has been shown to be a natural antidepressant.

Anyways, I've had some increasing anxiety that may be irrational. One of the machines that I have been using involves sitting up with your back and head against a chair and pushing up the weights. However, when I wasn't careful and lowered the weights down too fast, the weights hitting down made a shockwave that went through the the seat, and I've felt it in my head. Very similar to what you'd feel if you hit the backrest of a wooden chair if you were sitting in it.

Because my head doesn't actually move, but rather just feels the jolt, could this cause a concussion, or am I overreacting? It's a case of not knowing whether this is all my anxiety or not. And dwelling on it isn't helping any.
