Do you have experience with patients who have dated & are experiencing trauma from a narcissist?

Hello Amanda, you have shown great insight by seeking support with your breakup.

My name is James and I have been a therapist in various settings. While I have not knowingly provided therapy with a diagnosed narcissist, I do believe I have worked with a few over the years.

There is much to be considered in your situation, your age, your financial status, your other interest(people, family, career). Why did you let this person back into your life? What is your history with depression? What is your history with therapy?

The implication from your question is that you are aware that all change is a process. 

• You said the first step is blocking. I can't understand having literal trouble with that. On your devices you use the block or erase function. Done.
• Now removing all photos, letters, momentos, etc. Physical and electronic. 
• ENGAGE WITH OTHER PEOPLE! Follow your best judgment on how much interaction, but do not isolate yourself. 
• Expect waves and waves of emotions that go along with break ups, anger, sadness, regret etc. Emotions are simply Emotions, thoughts are neither good or bad. Just roll with the process (the emotional roller coaster) and know that this too shall pass.
• If you have deleted and blocked and are not isolating, then ask what your true desires are. If you want to be happy, get busy doing things that bring happiness.  If you want money, get a job.
• Do not take money, job etc from or with the person you want to distance yourself from.
• Become your own greatest admirer. 
• Your life is not about the other person.  You are going to have to grow and that generally is not a comfortable part of the process.
• Do not seek refuge in alcohol or other drugs.
• Give yourself time to grieve the loss, say...10 minutes per day ;)
• Considering your career field, with all of the current teleworking opportunities you may have options that you are not aware of.

This is the beginning of a marathon. Something about you has invited this situation. Something about you will recreate another like it if nothing about you changes. Feel good about your future, draw it, picture it, create it. Focus forward, not backward.

Sincere hope for your best outcome. 

James
