Time heals all wounds. Ive said it to myself over and over in times I've felt emotional pain, and it really does stay true to itself. If you have a painful memory attached to something you enjoy doing, just remember that its because that activity was something that you did during the period of time you were with a person/going through a stage etc.

You need to continue drawing and make new memories doing so. Its hard to explain, but you need to keep going even if it reminds you of what pains you. Thats the only way to break though that and be happy you know? Think of it as dealing with the emotional stress and building character.

Theres no need to give up a hobby because of some emotional distress. Work through it.

(dont mean to sound harsh, just straightforward)
