Couple things.

First off, your personality shows through very clearly, and you seem fun. That's always a win. You also have nothing that makes you inherently unattractive-- you've got your hair, and your features are symmetrical and balanced.

Second, I agree that something needs to happen with the hair. If you want to keep it long, which I think is fine, especially if you can drop some weight to bring definition back to your jaw and cheeks, you need to learn how to work with the texture. You appear to have thick, slightly coarse, wavy hair. I honestly don't know a whole lot about men's textured hair styling, since men typically wear their hair differently than women, but r/curlyhair could probably help you. It could be luxurious, I think!

The clear-frame glasses are not working for you. Stick with something the same shape as the sunglasses (those look good!), and try a contrasting color for the frame. I suspect it will be much more flattering.

As all of us chubby people know, getting fit will help us a lot in the looks game. You don't have super strong bone structure, so carrying extra pounds has an especially noticeable effect on the appearance of your face. Even ten pounds can have a big effect on facial appearance.

Also, you're still young. Most boys change a lot from 18-22.
