Am I Faking My Need for a Mobility Aid?

What makes someone disabled enough to use a mobility aid? I've been using a cane for a few weeks now, and yeah it helps a lot. But i can walk without it. So it makes me think- am i faking this for attention? Do i really even need it? Cause if i can walk without it obviously it cant be that bad, right? Plus, my family has been calling me attention seeking for it, and im afraid thats exactly what im doing. Like, yes my pain can get so bad i can barely walk sometime. But i pushed theough it for over a decade, so why shouldnt i just do that now? I dont know, im just very conflicted and scared and confused and i want some answers on if im being ableist and pushing myself into a community that i do not belong in, as many of my friends have started calling me disabled.
