anxiety often goes hand-in-hand with depression, which makes it attractive to sit and not pursue treatment- this is a bad idea, however, as you're wasting perfectly good time, days you won't get back without making some changes. You're describing anxiety symptoms, and the thoughts that go with them. There are many different treatments available for anxiety; it takes a little work to find a course of treatment that will work for you, but anxiety is very treatable. 'Getting your life back' is a good goal to start with, but treatment may allow you to set even higher goals like building the life you want for the future.
You definitely should go see a doc. Those feelings are not normal and it seems that you are not able to function as a result.
