Yes its possible. I believe a person can have many things that define who they are depending on where their mind is for example -

When I was a child who I was was my mothers child, my abusers victim, my sisters and brothers sister, my school friends friend, my teachers student.

when I first started working on the things that happened to me I felt I was a victim.

I also became a consumer - a person who was paying for a service - therapy, medical health, and so on.

As I got stronger at fighting back I became a survivor - someone who could stand up for myself.

When I was doing my public speaking engagements I was an advocate for past, present and future victims and survivors and for rights for children and child sexual abuse victims and survivors.

when I opened my home to my neighbors and friends and their chilldren I became a day care provider.

When I worked I identified with the roles of - secretary, custodian, teachers aid for pre - K through 6th grade, librarian, tutor,

When I was pregnant and my child was living at home my focus was as a mother.

Now one of my focus points is writing so I identify with the author role.

another focus point in my life right now is healing from DID. Unexpectedly I became an advocate, role model and teacher for other survivores who have DID.

Another focus point of mine is that I run a support group for women survivors so I am a facilitatior and advocate.

Basically throughout a persons life they take on many roles depending on where their focus is and their interests.
