Disabled kitten feeling sad

Hia, I have a chronic balance issue that makes it so I have to use a cane to walk around most of the time, very rarely I don't have to use it, and, unfortunately, more often than that, I can't even walk. This can shift extremely quickly and without warning.

Today, just before trying to make dinner, I ended up suddenly getting so dizzy that I almost passed out after trying to tough it out and had to lay down on the floor for 20 minutes before I was able to make my way to bed.

I cried loudly while laying there because these bad periods can last for days, and tomorrow I was going to meet my friends and watch the Amazing Digital Circus finale in the cinema, and now I probably can't.

I feel extremely guilty for this, like I'm not able-bodied enough for my friends to wanna keep being my friends. I just feel like a burden in their schedules if I can't be relied on. They say I'm not, but I can't help but feel like I'm not a good enough kitten.

Could some of you please tell me I'm a good kitten and not a burden?
