Why is there shame in wearing a wrist bandage for an injury? If that is the truth, so be it. If others shame you, the shame is on them for their lack of forgiveness or compassion for your pain. Get the bandage and wear it as you need it, do not make a big deal about it yourself. If they ask, give them a simple answer that you injured it and let that be the end of the topic. If they ask more questions, explain that your injury is your own business and not theirs. If they shame you, then you know the lack of compassion in their hearts and make the knowledge of their lack of compassion as "Square 1" in how you treat them in return. But wear the bandage. My sister did not properly bandage her finger and as a result it healed wrong and she now needs an operation to fix it right, where if she had worn the proper bandage it would have healed right in the first place. Do this as you need and if you have people shaming you for your pain, ask to be transferred to a different school. Good luck, but wear the bandage and heal properly, as this is most important for your own body.
