Everyone's traumas or disabilities are individual and I don't believe should be compared as "worse or better" than another. Not so much because the thoughtfulness to others you are saying have it worse than you, (although this as well).. but more because your experience of your trauma is related to who you are. - how you experienced it - how sensitive you are - how you've learned to cope with it Etc. 1 person can hate their stutter and another can love it (I sincerely love my stutter and have for the past few years). I bet there are many mute people who are happier than pws and I bet there are many paraplegics who are happier than people with every limb. Your suffering is dependent on how you relate to it. So to your question of "how to deal with the trauma from negative words" is of course tricky to answer without knowing why they stuck with you so strongly. You must've already believed this words to be true to some extent for the words to grasp you at all. I think the best thing you can do is stop surrounding yourself with negative people/content and start putting your focus and trust into people who have improved their life and/or stutter and see how they relate to their speech. If you listen to haters, you will hate yourself.
