I have been through the same phase in the past. A year ago, my girlfriend left me saying that she needed time to figure out things in her life.
She was looking for a job and said that because of the relationship she couldn’t focus.
So, she wanted a breakup. It was painful. I couldn’t sleep for months. I felt week and alone.
This went for months.
Then I decided, I cannot keep crying over past.
So, I changed things for me…
I started working out. Started hitting gym. Went on a bike trip with friends.
Did everything that I couldn’t do when I was in the relationship.
Started reading positive affirmations. They were really helpful.
Just know that all this is temporary. And one day you will over come all this. And things will be normal again.
