Hey Bryan!, don't even think that way, nobody should feel worthless, everyone has something to give to life, think of the positive things you could do & don't say there aren't any.
When I first started losing my hearing I really felt down & was upset, thinking my life is gonna go downhill, but I picked myself up by getting a good hearing aid & being more positive & thought, sod the world if I'm deaf, then I'm deaf & I don't care who knows it.
Remember, life still can be good even to us deafies, so pull your socks up & get on with life.
