(((((((((((((Zorah)))))))))) I can relate to this so much. I have an extreme problem with this, most especially if it is a new bill that the brain isn't accustomed to paying. Often I find that regular bills have been paid unaware but then others get overlooked. It's so everwhelming isn't it.
Do you have anyone there that can help you organize your bills? Maybe T? My T goes over mine periodically to help me stay in check. I also pay a lot of bills online or by phone by a paper list because of lost bills.
I'm so sorry you are struggling with this too. It's hard, I know. For me, it's also hard to trust anyone with knowing exactly how much I have due to some past issues.
Good luck to you Zorah and try to reach out to someone for help in this. They don't have to know all the details to help.
