I think the kind of feedback, and the intentions when asking for feedback, are important here.
You asked for feedback, received negative feedback, and instead of thinking "okay, what can I change to make that not true?" you seem to feel more like, "well, that sucks, why am I even bothering to make this?" If you ask for feedback, you have to be prepared to learn that something needs to change! If you're not interested in changing anything, then I honestly wouldn't ask for feedback. Why waste someone's time asking them their thoughts if you're not going to take their critiques into consideration? Just make the thing you want to make.
And that's okay to do -- it's okay to not seek out feedback because you've already made up your mind. Critique is extremely valuable, but not everyone's looking for it all the time, and that's okay.
On the other hand, it sounds like maybe this particular feedback is something you don't know what to do with. A lot of times reader feedback is like this -- readers and friends aren't creators oftentimes, and so the feedback they give might tell you when something's wrong, but not precisely what it is or how to fix it, and "generic and cliche" feels like that sort of advice. A story can be cliche and still well-told and interesting, so that's not the real problem -- what is? Are the characters not strong enough? Do the events and conflicts feel arbitrary rather than natural? Does the story contain no interesting revelations about character or consequence, and thus feel like the conclusion can be seen a mile off? Or is this story just not this reader's preferred genre? Those things are harder to pinpoint, but that's the actual issue, the thing that you can do something about.
So, don't ask for feedback if you're not actually looking for feedback. But if you do ask, and receive negative feedback, that doesn't mean "my thing sucks apparently I guess." Those are things you can try to figure out, and improve, and make your story better!! And if you ever get feedback that you're not sure what to do with ("they said my story is generic, but I like my idea, how do I make it less generic?") then there are a ton of experienced storytellers on here who would be happy to help you troubleshoot more specifically. ;u;
