Just stop and do a pct NOW! This is one of the dumbest things I have ever heard of someone doing. First thing deca needs to be run atleast 10 weeks. You said you did 500mgs/week of deca but I dont recall seeing deca dosed at 125mgs (you also said 4 ml a week). So you probably did 800mgs a week of deca for a pretty short amount of time for such a long estered compound. This had to shut you down hard. Then you began running 1gram of test everyweek, which that dose is only for very experienced users. Go to the pct forum and read as much as you can.
