Night time accident

So I have had LBL occasionally which has recently gotten a little worse. Last night I dreamed that I was going and YEP, woke up soaked. I had gone to the bathroom jut a couple of hours earlier. I have no idea how my bladder could have held so much, this was a monsoon, and I wonder if I am not voiding competely. Humiliating, to say the least. I ruined a memory foam mattress topper. Fortunately, I had a waterproof ALLEREASE zip around cover on the mattress. The king size memory foam topper was too heavy for me to dispose of and I had to ask me husband, who thank God had fallen asleep in the TV room. So depressed. Afraid to go to sleep tonight and was too embarrassed to ask my husband to take me to the store to buy nighttime pads. Just venting
