Yes this is very normal. I myself felt like this. For me, I lost my best friend, alcohol, the thing for me that cured boredom, and was there when I was happy or sad. It took a lot of work, and a lot of time to pick up and stick with new habits that helped to fill that void. Here is a link to a topic I made in my journey maybe everyone’s replies would be of use to you. Best of luck my friend! 
Also would like to add im coming up on a year sober and I do not currently have these feelings anymore. You will get on the other side of this if you just don’t drink no matter what!
