To take a stronger tack on what loonsun has said: IQ tests are bullshit.

Measuring intelligence - that is, the ability to find patterns and integrate experiences to synthesize solutions - is still an unsolved problem, and any psych major will happily tell you that - they’ll have learned it in their first course, even. No one’s figured out a way to do it that isn’t just testing knowledge instead of the actual “intelligence” of someone.

To give you just one reason they’re bullshit: there’s no IQ test in existence where studying for the test does not significantly improve your score. Clearly that means the test is at least in part testing what you know, instead of some “base aspect” of your mind.

Another reason often quoted is that tests made in different cultures produce different results for people who aren’t from that culture. So clearly, again, learned cultural knowledge - not some “base intelligence” - is involved in the test.

So instead of worrying about IQ tests, put them out of your mind. The only people who care about them are charlatans. If you’re having trouble functioning in daily life, you’ll likely go a lot further finding resources that help with the tasks you’re struggling with - which may not be easy, but will help you. A therapist may also be a good person to chat with this about - mine has certainly been a big help to me. Good luck!
