I'm almost 6 months out, and I'm in the same boat. I keep reading on here that it takes 2-5 years to get to a point where you "feel" healed. Being 8 months out...it is still very fresh.
One day I'm okay, the next I can't even stand to picture his face in my mind, and the next I want to leave. I keep thinking I'm losing my mind, and then I read posts on here and get encouraged that I'm normal. I hope you are posting and reading often, too. You need this.
I'm don't know if you're doing IC or MC, but that works wonders, too. With a little one and one on the way, it may be tough to get there, but you have to find a way...for your own sanity.
Please know that your emotions are completely normal. Eight months out might as well be the same as eight seconds!!!
