Struggling with Self-Consciousness as a Disabled Athlete

I’m stuck in a dilemma and I’m not sure what to do: I had decided to go out on a limb and tried out for color guard 2 weeks ago. the coaches know that I am deaf and that my elbows don’t fully straighten. I even emailed the main coach about it worried I was going to be an issue for the team but they seemed to be fine with it and I made it! (They’re losing a bunch of seniors next year, which is most likely why). This is where the chronic pain part is introduced. As I’ve mentioned before my elbows don’t straighten, but I also have hip pain from bilateral hip dysplasia. For the past 2 years, I have used a cane. It helped me get around, though an inconvenience at times, I loved with moving without pain. Until I had hip surgery last February. I was bed-bound for 3-4 months and it’s taken a long time to get back on my feet so I used the cane afterwards despite my doctor saying I need to “stop relying on it”. Before I knew I made the team, my mom had made a comment about the possibility they might not accept me into the team because I walk with a cane and I would need to be off my feet for long amounts of time. Ever since then, I got so self conscious and dropped using my cane instantly. I’ve been mostly okay, I think, my hip hurts mildly some days and others it’s worse. Though I’ve noticed that my cane was also making me have horrible wrist pain. I brought it up to my pediatrician, they did bloodwork, nothing abnormal. I don’t know what to do about any of it: I want to use the cane but I’m scared my team will see me as the “disabled kid” and think I’m not good enough or seen as issue. My parents/family don’t help either. Who are always telling me “You go on runs everyday and you need a cane?”, “You don’t need it, you’re just relying on it.”, “You joined color guard yet you want to use your cane?” or bringing up instances where I haven’t used it to use against me. Then the other issue is my inexplainable wrist pain, I can’t use my cane because of my wrist pain and unfortunately I can’t buy any other mobility aid because of my parents (I have a feeling they thought the cane was temporary until my surgery). So yeah, there’s my issue. Any advice helps, really. I’m lost and confused and now I’m even having doubts about being disabled because of one insignificant comment.
