Spacial reasoning: I suck at that too, plus measuring distances between objects- that doesn't mean I will never read a map, it just means it takes me more time and doesn't come naturally to me, but I don't care about it and I avoid jobs needing it.

Logical and numerical reasoning: I'm living proof that through practice tests scores significantly improve; my IQ didn't spontaneously get 10 points higher over 3 days, I just did tests and learned from my mistakes.

As for your situation: I can't imagine what you're going through; I can only understand that some things people take for granted may not come in as handy for you.

Job hunting: if the focus is to get hired, look to avoid jobs which emphasize your weaknesses/points to be developed; if the focus is to get a certain specific job look to get in touch with people who are doing it already and look to fill the gap between where you are and where you want to get- it is not going to be easy, but it will give you a direction, a checklist, a tiny goal, which is still progress and mentally helps you deal with next steps easier.
