Need some Encouragement and Maybe Some Tips

After my issues with leaking for seemingly no reason and the disaster I had at work this morning, I need some encouragement to keep trying with the cup. I'm certainly liking my Ruby Cup better than my Diva cup (even after enlarging the holes), but I have trouble getting them to pop open fully around my cervix rather than partially or against it. I tried one insertion tip for popping open using the punch-down fold (since I get the crooked cup problem with the c-fold) but I couldn't get it to open at all until I pulled it out and it snapped open, flinging blood all over the walls of the public restroom at work. After that horror story (including apologizing to my boss for my extended bathroom break) I just want to give up and not have to figure out the leaking issue either. Any encouragement or tips would be appreciated.
P.S. A detailed definition of residual slobber vs leaking would also be very much appreciated.
