I suffer from anxiety and depression and I am unable to sleep more than 4 hours, what can I do?

I am taking 1 mg Klonopin at night and 37.5 of Effexor 3 times a day for anxiety and depression which manifests itself with poor sleep and racing thoughts
. I have been on this for 2 weeks and I am still unable to sleep more than 4 hours a night. What else can I do?
