Unfortunately, I think people just grasp at straws when it comes to the post issue. I'm in that boat. I've sadly got some long gaps between mine (about 5 months) due to bills all coming within the same time frames and not paying the best attention due to a depression I went through. I also didn't realize not all mail counts. I kept a lot of things like letters about our English Heritage membership, job contracts sent to me, and personal letters. I spent a long time worrying and freaking out about it on this forum. Ksand24, KFdancer, and others have given me as much advice as possible. All I can do is include everything I have that fits the requirement, write an explanation, and hope for the best. I am also including a job contract and a personal letter from those long gaps just in case. We decided to risk paying the extra for an in-person appointment just because I could not deal with the stress of waiting weeks to find out. But that's all we can do.
But I can understand the sentiment that you got from facebook. The idea that you could be ripped away from loved ones and a life you are building because of something as stupid as not enough mail is so stressful and terrifying, that people want to believe they will be ok over hearing facts. I'm sorry they made you feel bad for helping. Everyone on here has helped me so much and I am holding my breath until July 18th, just trying to ignore the fear and anxiety. For better or worse, you guys will definitely know how it turns out asap. Hopefully it will be good news.
