[Scifi fiction that I found interesting]
Being psychic is tough. Your physiology is completely broken because humans never evolved to be what you are. Your altered nervous system requires blood content that none of your other organs like, keeping you in a perpetual state of poor health. Your continued existence is an achievment on the part of numerous doctors and nurses, all of whom earn many times what they would treating regular people. And if someone, anyone stubs their toe in your vicinity, you're gonna feel that.
Yes, hearing other people's thoughts can be kind of cool, but then you have to put in some effort so they don't hear yours too. Sometimes one can even hear other people's thoughts just by being close enough to an esper.
Levitating's nice, your shoes never get dirty, but you can't go outside radio-isolated buildings for longer than ten minutes, else the noise of every radio, TV, mobile and internet tower in range will give you a seizure. If you train hard enough you can even hear the radio.
Espers usually fall somewhere between unbelievably kind and terrifying. They're eerily polite most of the time, but can also hurt where nobody else knows to aim. They know exactly what you mean and how you feel, but then you also can't hide anything. They finish each other's sentences too. And when they talk to each other, it's weirdly mumbled and nonsensical like a person singing with headphones, because telepathy does the rest. Some don't need to talk at all, they just do it out of politeness.
