Hi doc how are you? I just wanna ask what is it...

Help yourself to unload your thoughts, restore your memories, and flip them in the subconscious and apparent. This makes you more attached, less sleepy, more tense and tired.
You must help yourself in forgetting that person and avoid being attached to him by leaving all the things that arouse your desire to think about it.
-Consider him past and finished and go down to your life and make him a reason for you to rise higher in life so specify another goal that you attach to, pray to, and succeed in achieving,
-Take care to develop yourself, set your life path positively, away from negativity, and resort to the past.
-Do your favorite sport and exercises, it will change your thinking and modify your mood.
 -Get close to your loved ones, be interested in reading and educating the partner, making a good choice, and take care of yourself and your life.
