It's okay to not do it. It's also okay to work on it (i.e. facing it). But school isn't necessarily the best place to do it. At your own pace, you may find your effort more constructive. - So you see, I'm not going to tell you either of the extremes ("do it", "don't do it"). I'm telling you to figure out your course in your own time. - Did your school therapist mention _speech_ therapy? Might be of benefit to you.   Btw. your English is quite fine. Keep that up. :)
