Griefcoaster - To Flash Pass or Not to Flash Pass?

So my therapist told me that the grieving process, like most things that are supposed to be methodical, is in fact not  a linear process.  Wikipedia describes the steps of grief, also known as the Kubler-Ross model, as follows:

The progression of states is:^[2]

1. Denial – "I feel fine."; "This can't be happening, not to me."
   Denial is usually only a temporary defense for the individual. This feeling is generally replaced with heightened awareness of positions and individuals that will be left behind after death.
2. Anger – "Why me? It's not fair!"; "How can this happen to me?"; "Who is to blame?"
   Once in the second stage, the individual recognizes that denial cannot continue. Because of anger, the person is very difficult to care for due to misplaced feelings of rage and envy. Any individual that symbolizes life or energy is subject to projected resentment and jealousy.
3. Bargaining – "Just let me live to see my children graduate."; "I'll do anything for a few more years."; "I will give my life savings if..."
   The third stage involves the hope that the individual can somehow postpone or delay death. Usually, the negotiation for an extended life is made with a higher power in exchange for a reformed lifestyle. Psychologically, the individual is saying, "I understand I will die, but if I could just have more time..."
4. Depression – "I'm so sad, why bother with anything?"; "I'm going to die... What's the point?"; "I miss my loved one, why go on?"
   During the fourth stage, the dying person begins to understand the certainty of death. Because of this, the individual may become silent, refuse visitors and spend much of the time crying and grieving. This process allows the dying person to disconnect oneself from things of love and affection. It is not recommended to attempt to cheer up an individual who is in this stage. It is an important time for grieving that must be processed.
5. Acceptance – "It's going to be okay."; "I can't fight it, I may as well prepare for it."
   In this last stage, the individual begins to come to terms with his mortality or that of his loved one. 
It seems to be a one-step-forward, two-steps-back process.  Sometimes you're fine and sometimes you're not fine and in between you're numb and it sucks.  Which is why I would like to add a few steps.
6. Sheer Bliss - "I'm on cloud 9." ; "I had the best sex of my life last night." ; "Ohmygod, today I had a total blast and didn't even think about ________."  In this stage, the griever may have had a positive encounter with a new friend and/or gone an entire hour/minute/day without reciting the grievee's phone number (which he/she knows by heart, of course).
7. Drunk-Dialy-ness - "Heyyyyy, it's me. I really, really miss you. I am going to die alone."  This occurs when inebriated and should be avoided at all costs.  Other symptoms include unsolicited booty calls to otherwise unsuspecting male acquaintances.
8. Apathy - "I would totally not care if he showed up with another prettier, skinnier girl on his arm." ; "I don't care if I never see him again." HA. HAHAHAHHAHAHAHAHAHAH. Who are you kidding?
9. High-and-Mightiness  - "I can do way better." ; "I can't believe I ever even associated with that person." ; "I'm so much hotter/smarter/decidedly not going to die alone."  In this stage, you have ingested too much cocaine and/or self-indulgent therapy.  Check into rehab/get a new therapist.
10. Move-on-ness - "This didn't work out, but I'll be fine, and find someone who is right for me."  Not to be confused with acceptance, this stage applies uniquely to relationships in which one person was ready to bolt and the other wasn't.  It certainly won't happen overnight, as move-on-ness takes time, patience, and becoming reacquainted with yourself.  Lord knows I'd like to get there.
