Look, if you are serious about meeting girls you first need to work on your attitude a bit.
First, stop feeling bad about yourself. Ambrosia hit the nail on the head when she said you need to be confident.
Hard of hearing? well there is not much you can do about it so might as well accept it, finally.
You can either go to a HA seller and pick the best HAs for your hearing loss type, or try out for CI.
OR, you may turn your life a totally different way and became Deaf - keep signing, learn to sign fluently, go to Deaf uvi etc.
OR, better yet - ALL of the ABOVE!
If I was 30 again I'd go this way for sure.
Then, once your self esteem soars to sky's the limit - you'll find girls will start gravitate toward you like moths to a flame.
