Anyone who got approved for disability quickly?

What disability do you have, and how long from applying to getting approved? Did sending in any paperwork help speed it up? I sent a letter from my psychiatrist weeks ago, and still nothing has changed. I have ptsd, ocd, adhd, and I guess I have to get tested for autism. I also have heel spur and severe bladder pain but the drs wont write letters for me for those. This system is so messed up. We should be getting decisions within a few weeks, not years. There are ways to speed it up, but the government is putting on the effort. Ridiculous
