There is nothing wrong with remembering your past and acknowledging it. It's okay if things that you've lived through still hurt and bring you pause. But you should not allow your past to overrule your present or your future. It can take some people longer to get over past damage or loss or injustice, but that does not justify clinging to your grief and pain so tightly that you not only fail to heal but also do more damage to yourself.
While painting and sketching will always remain a hobby for me, they are still activities in which I want to develop my skills. As I've explained previously, these types of visual arts can help me with my writing process, particularly when I'm trying to hammer out details or rid myself of a distraction. Over the past few days, I have been doing the latter, working on a fanart project that has been distracting my mind from my current manuscript.
