Narrative:

I received clearance down to 2000 ft and I busted limit down to 1500 ft. I was also told by approach to intercept NDB runway 17 at sgr and execute visual approach. The conditions were very bumpy and I had a sick passenger. Approach notified me of the altitude violation and I climbed back to 2000 ft. The controller was obviously upset. Upon climbing back to 2000 ft, I was told to immediately descend due to oncoming traffic that was not with approach. I was told that 'targets will converge.' after avoiding the traffic, approach told me 'radar service terminated, squawk VFR, contact tower at 118.65.' I notified tower that I was 4 mi out inbound for landing. Tower cleared me to land. Tower then came back and asked if I was canceling my IFR flight plan. I told him yes, that approach had canceled it by telling me to squawk VFR. He told me approach had just called him and told him that I had squawked 1200 without notifying them. I explained that approach had told me to squawk VFR. Tower then told me that my report of 4 mi out was bogus because I was really 5 mi out when I reported. Upon landing at sgr, there was a special event going on with a lot of resulting traffic in the area which contributed to everyone's stress. My flight plan had originated in kansas city. Sugar land is my home base.

Narrative: I RECEIVED CLRNC DOWN TO 2000 FT AND I BUSTED LIMIT DOWN TO 1500 FT. I WAS ALSO TOLD BY APCH TO INTERCEPT NDB RWY 17 AT SGR AND EXECUTE VISUAL APCH. THE CONDITIONS WERE VERY BUMPY AND I HAD A SICK PAX. APCH NOTIFIED ME OF THE ALT VIOLATION AND I CLBED BACK TO 2000 FT. THE CTLR WAS OBVIOUSLY UPSET.
