Half Sleeve Tattoo Removal

I just turned 21 and have this huge tattoo that I'm going to have removed with laser. The Aesthetician I saw is suggesting Picoway as it operates at a 1064 wavelength and is best for targeting black. I have done tons of research so I know I'm going into this using the best available resources. I can't believe I'm sitting here today. I'm writing a review mostly to connect with others because this is going to be such a long process of what I have already been struggling to accept about myself. I have the worst scar/red pigmentation on my arm that I was always so self cautious about. I was only beginning to be truly happy and love who I am for almost two years and knew that If I could get rid (even though lasers from the past left me scarred trying to get rid of this pigmentation in the first place) it would make me almost entirely content with myself and my body image. I realized after not getting rid of the scar that I would be better off getting a coverup. I researched artists like crazy and found one who I thought was awesome and had a consultation. The artist seemed at first, like he was going to take care of me and help me out. I gave him two weeks with my idea (Roses, a handmirror and pearls) which was pretty simple, to turn into a really great piece. I showed up three days before I was scheduled to get it done, and he didn't have it drawn up. He said he'd have it done the next day and he did, but being as busy as he was I think he could have thought it through more. I hate myself not only for the fact of not standing up for myself but because there were so many red flags that I am a complete idiot for not taking them to heart. I am still in shock, I'm depressed, I have anxiety from hell and I literally just want to crawl in a hole and stay there forever. I was only trying to do what I thought would make me happy. Here goes a long and terrible experience while continually hiding my arm for another year or so. I would love some feedback and just people to talk to who actually understand what I'm going through! Thanks

Here are my before pics. Going to be a month or so before I begin treatments. Wish me luck!

Has anyone heard of this place? They seem very reputable online and I think it would be worth the flight if they are motivated to get me the best results as soon as possible.. it would be a long flight but I can't really get myself to trust the local laser spas here.
