If u r loaded with projects and working allot of ot and loosing focus and creativity.what is likley happening dizzy and tense as well?

You are likely: Overwhelmed and trying too hard and then it becomes like a cycle that makes it really difficult to focus and become creative. That is when it might be important to take a step back and maybe even take some time off.

Very likely: Everyone has a limit and rest is a very important thing, especially sleeping enough, and exercising, or just simply being a human being rather than a human doing... What you are experiencing is called by lay people: :BURNING-OUT"

Stress disorder.: Working too much while it may help you get ahead can take a toll. Many people start to feel down or stressed out as the pressure or tension mounts. Need to take time and retool your mind as well as your spirit. Have some fun, relax and take time for yourself. If you don't things may get worse and come to a complete stop. May well have depression. See your doc.
