I do not know you or the people involved, but I think people are understanding IF they are communicated with. As long as people are aware of the fact that health issues are delaying orders, they are usually patient, but if their pm's are ignored or calls not returned, then they get frustrated. For people to see you reading a post and not responding is probably very frustrating for them.
I hope your health improves and you get back on your feet and back up to speed,
