Suggest Treatment For Difficulty In Sleeping And Anxiety

Hi there I m currently clenching my toes over so hard at night that I m waking up in severe pain in my toes, I also clench my jaws. I have terrible trouble sleeping and find it hard to go to sleep and then I tend to wake up a lot through out the night. I do exercise during the day but it does not seem to be helping with my sleep problems or anxiety. I also take 150mg of Zoloft a day. Due you think I should see my GP, what do you think they will suggest. Thanks Kindly.
