Goodday Friend, i can understand your suitation.
Be aware that we can never erase or forget the past. In the process of forgetting the past we infact add more and more strong memories of that suitation or person and get into depression.
But there are alternative solutions to overcome this problem and focus on things that matters or make sense for you. This will be achieved by counselling and psychotherapy solutions.
Be positive. You will be alright soon.
Feel free to reach me if you are willing to make few changes in your mindset, lifestyle, dietary and following few therpies to come out of this suitation
