Tattoo idea

Hi! I need some ideas for tattoo to cover my scars(self harm) on my arm.

I have battled with depression, anxiety and borderline personality disorder and I am trying to get better and move on from it.

I want to be healthy and happy again.

I need some ideas!

I already have a small tree and flowers on the wrist but rest of arm is blank and full of scars

I added an old picture of when I got my tree tattoo done and you can sorta see the flowers too.

Thanks!!

Edit: the picture seems to keep cropping, but they are both on my wrist and fairly small ish

Edit: sorry I should probably mention my other tats. I have one my back with roses and a quote and a half sleeve of flowers started on my other arm :)
