Lol nah you seem fine, get the cat, please don't let a single internet comment deter you. Explain your situation to someone at a shelter/rescue and if they're okay with you having a cat, then its probably fine.

Its better to have a cat in a home that barrely meets the minium requirements, rather than having a cat be put down or stuck in the shelter for a long time, possibly for the rest of its life.

When you getting a cat, you're not just helping that one cat, you're also freeing up that space for another cat to be saved, instead of being put down.
