I am 23 years old recently(July 2016)passed out from college and have no job. I was quite good in studies during my school but various issues made me neglect studies in College.I got into a quite good college but substandard in my opinion for it lacked the quality in teaching I seeked. I wanted to study in world class institute. As a result of which I kept myself distanced from teachers and studies. (Since childhood I was among the topper of class and highly rated student among teachers). My below par performance in College made proff think I was a weak student in studies but that never shook my confidence since I was still learning non College related constructive thing and was active in co curriculur activities with good amount of success. In the meantime personal(girl friend) issues together with not so good academic results made me resort to marijuana. I got heavily addicted(daily above 10 bong shots of high quality weed) for 8 months. In the later part of my addiction, I used to think of ways to achieve big things and fulfill my dreams of being world famous and nothing else.
To motivate myself to strive for excellency and perform very good in a highly competitive entrance I started thinking too much.(I am an avid thinker anyway). Since March when my girlfriend left me, most time of the day I kept thinking about how to get back my lost glory in academics. All my school friends are well placed and studying in top universities in various parts of the world.
I stopped taking marijuana after passing out since I had made up my mind to study religiously to get into a top post graduation college to pursue my dreams and do justice to my talents and skills. I enrolled myself in coaching institute to prepare well to crack the entrance and performance in coaching is well above average. This shot up my confidence and I started dreaming/thinking too much of success and contribute things for betterment of people(social work). I must say my mind is hyperactive ever since childhood which made me very good in debates, extempore, group discussion and getting new ideas. I had this habit of analysing day to day issues to great depths since school days mainly to introspect myself. This habit of analysing things exponentially increased since my engagementy marijuana. I started analysing football, politics, social issues etc to a great extent that eventually I started giving answers in Quora.
The problem started last 1/2 weeks when I realized I am thinking way too much. I can't keep my mind at rest even for a single minute.Then this started hampering my concentration to study. At times I thoughts come to my mind that I have lost control of my brain.My mind keeps analysing every small and trivial things which makes me mentally fatigue. I should add that since August I am staying at home after returning from college. I have become little rude and impatient and small things made me angry. Maybe this was withdrawl symptoms of marijuana. Now I am more stable in terms of my anger but just that my mind can't stop thinking.
Is it performance related stress or high residual dopamine in my body. I am also worried of getting schrezophenia.
Please respond. I need Help.
