I think few months isn’t long enough. I also think marriage even a short one like yours is different grief than just a relationship. You grieving what you thought the future was supposed to be like staying for life. But then it didn’t work out, So you aren’t only grieving what happened but also grieving your future that you planned on spending with person. So it’s perfectly normal to feel yucky right now. Few months is nothing.

There are support groups for recently divorced people. Maybe look for those. I’ve run into a couple ones on meetup. I was looking for a widow support group for a friend and saw one of those. There might be some by you.
