Are there any telecomm/Internet security/hacker experts who would like to help me with counter-intelligence?

Apparently I am under some sort of sneaky hacker attack where someone is trying to spoof email messages and caller ID phone calls between me and women I know, apparently to cause disruption or something. I’m a little out of my depth in terms of being able to gain information about who has caused the calls and emails. Anyone have unusual knowledge know how to figure out who is placing calls and/or emails? I will want to limit details to private messages.
