This is a really good post popcorn - it really shows creative action in work, while simultaneously demonstrating the grief process versus being lonely.
I think I just miss 'somebody' being in my life. I think that I want to share my achievements with someone, not be sitting here alone wondering why I bothered.
Any thoughts on this or tips on how to get him out of my mind?
We tend to think of the last person we were with when we feel lonely - this is human nature, honestly. Humans like to couple/partner up - we are built that way.
So, you are lonely right now - the truth is, I tell myself when that happens - it will pass. It always does. Use your past success as an indicator that it does pass.
So, maybe instead of "getting him out of your mind", try refocusing. Kinda like if you take a picture of a flower and a tree - the focus is of the flower, but you want the tree - so you refocus. Your life is the picture, you feel lonely (he comes into mind) - instead looking at him, look at the flower.
Keep in mind, sometimes we need another round of processing. Sit with the emotions, feel them, cry if you need to - then let go and refocus.
Glad you have been doing well the past couple months

This is all a process, not an event - this lonely will pass by, it always does
Peace,
