This can be a very dangerous state of mind to get in. If this is as significant as has been made to sound it can be very serious.
Surgical addiction. A constant pursuit of beauty through surgery. Many woman fall victim to this. Sometimes the surgeon themselves may contribute. Dr. Zukowski put stars in my eyes when he said he didn't know how to make me look feminine through surgery. He could only make me look beautiful. A nice touch, that. It almost always seals the deal.
But cosmetic surgeons especially are very wary of someone wanting constant updates, changes, improvements. Hoping that the next surgery will finally make them beautiful. It would never be enough.
If this person is in therapy, encourage her to discuss her body image issues with them. This doesn't sound like it is a strictly transsexual issue, but one of self denigration and hoping that external, not internal changes will fix everything.
