Hi there,
I understand it is difficult to be vulnerable, especially when you feel rejected. It is not unusual to feel the way you're feeling after a break up, however you need to visit a psychologist for professionally determining if you have Clinical Depression or not. For the time being, it'll be fruitful to keep yourself busy doing activities that you enjoy doing and spending more time with reliable friends and close family members. Most of the times when you feel sad or lonely in life, it is better not to isolate yourself from those who love you. I hope this helps you.
Next Steps
Try spending more time with reliable friends and close family members.
