Crying right now..

I just back from follow up appt with my surgeon. I'm feeling low so sorry if I go on and on. I'm really tired. I had an excision a couple months ago for scar. first follow up at a month, it looked ok but told doctor about one part looked indented. he said it's due to swelling, and he'd laser but not for a while. Wait it out. Today I went back, and he admitted that that part still looks a bit depressed. Here's the part that upset me. Before, a couple times, he said he could co2 laser this scar. Today he said no, because of my olive skin tone and possibility of pigmentation issues, he'd do something else.

Has anyone with olive skin tone gotten co2 safely and successfully? From what I've read, you can have it done if you start hydroquinone, etc, prep to your skin a while before starting treatments. This is the only thing that I've read from people here, and elsewhere, that has helped deep scars - co2.

instead he said He he would use a sublative 1540 (I had wanted ablative), and occasional zaps from 2940 which he said would accomplish same as co2, but without the downtime and pigmentation dangers. I looked both up and they have terrible reviews on realself.com - the first one is a Palomar Lux and the second is an Erbium yag. I thought yag might be good, but every study I'm reading says its effects on deep scars are minimal and less than co2. OMG I just lost it!! I thought I was almost done with this but it feels like this doctor isn't wanting to give best results. I wonder if, since he's doing the laser for free, he doesn't want to do co2 because I wouldn't be paying for it and co2 costs more?

he was pretty cold today and didn't give me much hope. I was hoping to do c02 then be done with this. I've been dealing with this for so long and have gotten so far...until today I'm so upset I just scheduled an appt. with david rahimi, even though I didn't want to but he's the only dr local to here that people keep recommending on acne.org. I shoujldn't be bouncing from doctor to doctor, I wish my own doctor would just do it! I asked if a spot test for the co2 would be possible to see what "pigmentation" issues it could cause me, but he said if we do that we might as well just do the scar but he just does not seem to want to do c02! it was my last hope. Help:( If you know any other good laser doctors in CA please let me know. I want to die today, I'm so tired.
