I get what your saying Meebs and you shouldn't have to resort to anything dramatic nor should you be pushed to the point of meltdown because people aren't believing you when you tell them how you feel. I know this situation very well
Sometimes it may appear to others that you are managing or that you are now ok but only you know for sure if this is the case.
As for a disability claim, I hear that it is harder now to get approved. Maybe that's why I see all these commercials on tv for lawyers and agencies that will file claims on your behalf and even fight for claims that have been denied.
Is getting approved for disability benefits a necessity right now? If it isn't why add more stress and anxiety? If it is, maybe a third party (friend or relative) can help review the claim with you and the reason for rejection. Perhaps file an appeal.
