Agreed, you're definitely having issues with depression or something similar--at any rate something that needs to be seen to, acute rather than life-long like AS is. Get yourself a psychologist and address this immediate crisis. Once you're back to a more stable situation, talk about the possible AS... Think about it like this--If you come in to the emergency room with a broken arm, you need to have the arm seen to before you address long-term health issues that aren't putting you in immediate danger... Of course, knowing for sure whether you have AS can be quite a reassurance, so it could be part of what can help with stability long-term. Find a doctor who is willing to listen to you and take you seriously, and make your safety your first priority. Try to stay out of the hospital if you can; though it is a reasonable last resort when you are suicidal, it does not particularly help you learn how to manage your own problems.
If anybody makes accusations of "manipulation" in any way that suggests your actions should be ignored, dump them. Even when people do manipulate others, it means something; they do it for a reason, and the proper response is to figure out what purpose it serves for them--not to ignore them and belittle them for doing it. So even in the absolute worst case, if you actually were being manipulative, they still did not respond to it properly. I actually see no evidence that you were; and that is not surprising because "manipulative" is a common complaint made by incompetent psychologists against "difficult" patients. Often times, it means little more than that you annoyed them in some way, probably by not being properly submissive. A doctor who accuses patients of manipulativeness in this fashion is not a competent doctor.
