We can understand what you are going through. Past bitter experience will keep retrieving in your mind as and when you meet or talk to people around you. You tend to link your past experience with the present situation. Consult a Counsellor, vent out all the past issues and see how you can move ahead in life.  You are absolutely fine, just need help to empower yourself to handle situations. Be blessed.

I understand how you feel. I would recommend meeting with a therapist. Having a regular routine including exercise, meditation helps immensely. I would also recommend this book called “ you will love again” by Dr. Shyam Bhat.
