Oh, I'm so sorry that you went through that. (hugs)
As someone who also lost their identity in their relationship, that's some great advice. Aside from a painting I'm finishing up for a (very patient) MLer, I haven't really been doing much drawing or painting lately. As soon as I'm done with that project, I'll probably pick something up again. Or dive into adult coloring like everyone else here. lol
So many hugs. I've been there and it's really hard. Take all the time you need to grieve, feel the anger, enjoy the time it takes to get back to being you. I started a private blog and wrote my ex several letters on there and found that helped. There was no point in telling him how awful he was and how he hurt me, but I needed to get it out. The ladies on MM, many of whom are now on ML were amazing and I couldn't have gotten through it without them, so lean on the board, I know they'll be here for you.
