Glad to hear you are ok man. A good idea next time you do a deep dive or to your maximum depth or any depth for that matter is to loosen the quick release on your weightbelt and holding it in place with your free hand as you start your return to the surface. If you do this and you black your slack hands will automatically let go of your loose belt and it will fall off allowing you to continue your float to the surface.
Hope to hear you get back in the water soon and good luck
