I know this is a place for stories but this is true and I need help, It involves angels

Please help, I fear that I dont have much time.
I dont know where else to turn, so I'm reaching out for help. Someone very close to me believes that he and I are angels, and told me so about a year ago. I still dont feel convinced that this is possible, but there are indications to its truth. First I need a way for me to get solid proof of this. Others say I should know already but my mind and body feel torn. More importantly me and others dear to me have been followed by shadow like figures, but only when im near or can see them. They are becoming more aggressive, moving closer every night. I fought one recently, I tried every spell and called every holy name I knew but it didnt stop untill I reached for my sword and pushed it back. I tried to stab it and the blade shattered. Spells wont help me I need something solid, a weapon I can use to protect my friends and family.
I feel that I have no where else to turn.

Who am I? Why am I being targeted? Someone out there has to know!
