Putting aside the personal family problems (LW needs to lock down all forms of identification, access to bank, etc and go no-contact with Dad and probably no or very-low contact with anybody still in touch with him) I wonder if LW can start applying to jobs as I. Middlename Lastname instead of Firstname I. Lastname. I do know people who have done that either because they don't like their first name or because this is a racist society and their first name is not helping them get hired, and it might keep people from realizing those bad fake applications are the same person as the good ones.
