I think it gets better so long as you focus on yourself. For me, I was so wrapped up in her, her, her that by default I was already deflecting my own feelings.
In time, I worked hard to take things day by day. I also worked hard on understanding my feelings and letting them play their part. This may sound strange but it was important for me to understand how my feelings made me feel.
I still have bad days but since I'm more in control of myself, I have way more better days.
I wish you the best.
