Tattoo to cover scars-TW self harm

I have battled with depression since I was about 13 years old I am now 22. It’s a lot better but obviously I still have my bad days. Well two years ago was the last time I relapsed doing self harm on my forearms. I’m thinking about getting a tattoo to cover them up also that will encourage me to not harm myself again. However I don’t want to look unemployable because I plan on going into becoming a social worker.

I was thinking about a tattoo like this. Where the tattoo is positioned in the photo isn’t where it would be on my arm, mine would be on front side of my forearm so it would definitely be visible. What do you think? I’m nervous about it but I think it would be a good way to motivate me to not harm again I’m just worried about employability.
