Most of the time, people don't give feedback because they either 1.) don't know how to properly critique (which is a thing - giving a good critique takes practice) or 2.) don't want to give a critique where the artist perhaps wasn't looking for any, so don't want to come across as rude.
If you're really looking for feedback, then most of the time you have to ask for it, either by submitting your work to a review website (ex. WintreKitty Reviews... Pros: you get a review from someone experienced, cons: these sites often have long waiting lists) or just asking when you upload (Pros: You get to hear lots of feedback from many people right away, Cons: Not everyone knows how to critique and you might not get as much of an in-depth review as you'd like, some people will literally just say "looks good to me" and move on without expanding on the why's).
Anyway, I'm gonna stop beating around the bush here and give you a review.
What I like: The art is super nice. Very colorful, with good layouts. You seem to have a good understanding of basic art "rules", including anatomy, coloring, lighting, line thickness, etc. Good job, keep it up 
What could be improved: There are a couple spelling errors here and there, that I feel you just probably missed while working on it. We as the creators tend to miss these things because we know what we want our characters to say, so we tend to miss these little errors (I do it a looot more than I'd like to admit). Make sure you do a thorough reading of your work, actually reading the words and letters, before you finalize it. Bonus points if you have a friend to look over it with you. There are also a few instances where the grammar could use some work (when Clarisse is giving their speech about bullying, they say "There are many forms of bullying, but no one is less severe than the other." 'No one' implies a person whereas the context is within the reign of bullying/abuse (which is a verb/topic) so the more appropriate phrasing would be "None of them are less severe than the other". Reading these sentences aloud can help you figure out what might work and not work (if they don't sound right when you speak them aloud, then they could use tweaking).
Other than that... honestly, you've got a nice little comic here. It's got an open topic that many people can relate to, in a modern day setting, so it's not like the genre you've chosen is too niche. If you're trying to get a readership growing, and wondering what you could do better to help pull in readers, then I would suggest just improving your presence in the community. Do you ever share your updates on Facebook/Twitter/Tumblr/etc.? Comment on other creators' works and take part in community discussion? Or are you just going from update to update? If you're not doing any of these things, it's not the end of the world per se (specifically the taking part in the community part), but it definitely helps to build a presence in the community, so that even if people may not read your work right away, they can still go "Yeah, I know that creator, they make [insert comic here]". But most people who know these creators will at least read some of their work (there are only a few creators I know by reputation whose work I don't read, but even then I read their work in the past and just don't read it anymore, for whatever reason).
Soo yeah, that's about all I've got for you! You're off to a good start, better than a lot of people who come in here looking for reviews, so maybe it's just that that's making it hard for people to give feedback. That being said, there are always ways to improve, so just keep up what you're doing, don't be afraid to look for new techniques and methods; you'd be surprised what you find works for you, even when you least expect it
