Preparation for Decision a few days after. Just today April 17th got 
Pending Decision Approval. My doc even agreed it got worse. whats odds of me getting 100%?

The odds are good, provided that you meet the criteria for 100 percent, which is "total occupational and social impairment".  

This means you would not be able to work, for a starter.  Are you working?  

Its impossible to estimate your chances without knowing more.
