mobility aids

I feel like I could really benefit from using mobility aids (specifically forearm crutches) for my bad days, but I feel like i’m not disabled enough to use them. I feel like if I do I’ll be taking them away from those who need them. I honestly feel bad about using them. But every time I see someone with forearm crutches I wish it were me because they could help me so much on my bad days and with my random joint pains. I’m pretty sure I have ehlers dahnlos, I have some of the symptoms and it runs in my family. I’ve started thinking about them, like a lot. I don’t know what to do.
