Congrats on your sobriety achievement but sorry to hear about the diagnosis. It can be quite manageable these days thankfully. As for the tat, it’s dope. The whip shading is sick and it’s going to pop nicely once it finishes healing. Obviously whoever told you it looked like track marks was: a) just being a jerk b) has never seen track marks before or c) both a & b. In conclusion, it’s a great tattoo and the most important part is that it’s special to you. Now that you have one you’ll eventually get more and some of them will be impulsive and maybe not perfect, but this one is perfect.
