Granted, you are a slimegirl. Slimegirls might be made of, well, SLIME - specifically slimey amoeba-like cells; but they do possess some organs, the main one being your slime core which is the equivalent of the human brain.
Unfortunately for you, you suffered an accident that damaged your core, and specifically a part of it related to sensory input. See, slimes are capable of feeling vibrations in the environment, which gives them a sort of "sonar sense". But this sense has been severely weakened, giving you a sense of touch equivalent to that of a human being. This means no cool sonar ability... and no hearing, since sounds are a form of vibrations, and you would normally "hear" by feeling vibrations through your slimy body. You are 100% deaf. Among other things, this makes you unable to hear or "feel" incoming danger unless you can actually see it; and it makes you talk awkwardly, since you can't hear what you are saying or how you are saying it.

But it's not all bad. You are surrounded by kind and supportive friends/friends-with-benefits/lovers, who can empathize with your plight. Mostly because they're all monsterfolk with some kind of disability. Like the oni woman with the heart condition that heavily limits how much she can strain herself - which is a problem for a species such as onis, who are full of pent-up energy and aggression that they usually release through healthy physical activity.
Or the werebat nerd: she's blind from birth, but that's perfectly normal, since her sub-species is naturally blind and possesses super-hearing and a sonar voice to compensate. Unfortunately for her, her schizophrenia is NOT natural, and it causes her mood swings and auditory hallucinations, making her hear/"sonar-see" things that do not exist.

...What, were you expecting traditional amputee stuff? Fiiiine, I guess I'll add an armless sphinx, who is used to her reputation as a refined high-class girl and wouldn't be caught dead using her mouth to grab things.
