I was flying visually from ZZZ along the shoreline to ZZZ1. The entire flight except for the last ten miles was VFR. I was using my ADSB to check on the weather and airport conditions the entire route. Up until the last few miles ZZZ1 was reported as VFR. As I approached within 20 miles the airport flag switched from VFR to MVFR. I had been trying to contact the Control Tower but I heard no response. I did hear another plane ask to land under SVFR. I finally able to contact ZZZ1. They told me that they had heard one of my previous calls but I didn't hear them. At that point they told me the field was now IFR and told me to contact ZZZ2 which I did intending to file an IFR approach plan. I contacted ZZZ2 and they told me to contact ZZZ3. By that time I was entering cloud cover and attempted to turn back but I momentarily lost control due to severe wind shear and dropped about 500 feet before I was able to recover. I became somewhat disoriented as my autopilot wasn't working correctly and I required ATC to help me escape my predicament. I regained control of the plane; was expertly directed by ZZZ3 ATC and was able to safely land at ZZZ4. As an aside; I called out to ZZZ3 multiple times stating that I needed help but they were so busy with all the other traffic it wasn't until after I momentarily lost control of the plane that they finally realized that I was in trouble and then devoted their attention to me. I thank them for that but a more timely response by ATC in general allowing me to file IFR would have prevented the subsequent events. And; yes; if I had asked earlier it could have been averted too but there were no issues until the very end so there was very little time by either party to have resolved the issues sooner.
