Help please

Hello, I am a 20-year-old male who used to be happy and academically successful. In 2021, I experienced severe constipation for no known reason, and it lasted for a month, during which I suffered greatly. I tried taking laxatives in liquid form, but they did not help. The constipation was so severe that I only drank water throughout the day, and even when I eventually went to the bathroom, I still experienced constipation.

After a month, the constipation resolved on its own, but I began to notice a loss of concentration and a decline in my memory, accompanied by feelings of depression. At that time, I did not fully understand what was happening to me. I eventually consulted a psychiatrist who prescribed Lexapro, and while I did notice some improvement on the medication, I still could not comprehend the root cause of my condition.

All of this occurred at a time when I desperately needed my memory and concentration as I was preparing for the General Secondary Education Examination in Jordan, which determines one's future in university. Despite my difficulties, I forced myself to focus and managed to achieve a high score that qualified me for medical school. However, for the past three years, I have felt that nothing has truly changed. Perhaps my symptoms are less severe now due to the antidepressant, but I feel that I was one person before and have become someone entirely different because of what happened.

Recently, I began reading about irritable bowel syndrome (IBS) and felt that I started to understand my situation. It seems that my excessive consumption of substances that irritate the colon may have led to chronic irritation, damaging the serotonin-producing cells in my intestines, which in turn caused the symptoms I previously described.

I currently feel depressed because of everything that has happened over these years. Ultimately, all I needed was the psychological strength and determination that I used to draw from within myself during those difficult times, but now I am seeking a definitive solution. I want to return to the way I was before that damn constipation!
suicidal thoughts come and go , focusing zero , and we all know that medical school needs every drop of your focusing and concentration so that you can get good grades.

Thank you
