Why do I overload my brain with so many thoughts?

Hi doctor,

I was diagnosed with essential tremors, and I am always distracted. I suffer from tics and obsessive, repetitive movement like blinking, clenching my fist, breathing tics, obsessed with personalities and how consciousness works. I always focused on my bodily sensations, like how my legs feel pressed against something. I have trouble finishing a thought. I always try to understand difficult things, such as how consciousness works, the concept of a soul, solipsism, how people learn a language as babies, time, infinity, what makes people different, the purpose of life, what makes people tic, personality disorders, etc. I am very into, the MBTI, Enneagram, global 5 type, Sigmond Freud's id, ego, and superego, Maslow's hierarchy of needs, horoscope and other personality assessments. I basically try to dissect people through observing them like you would disassemble a car and understanding how each piece works and then putting it all together and seeing how it all works together. I am always placing people into categories. I sometimes would watch a movie and carefully observe a person's tone, body language, gestures, laugh, eye movements, facial expressions and try to get deeper into who they might be and why they are like that. People give me a feeling, and I sometimes categorize them like the four elements, water, wind, earth and fire. Angry people like fire, passive people like water, happy outgoing people like water, and reserved stubborn people like fire. I am always placing myself into people's shoes and seeing a scenario as if I was them and they were me. If left alone, I could fry my brain with an overload of thoughts.

Thank you doctor,

What do you think I have? And will these drugs do me more harm than good with side effects? I took an MRI from a recent car accident and they did not find anything wrong with my brain, not with EEG. So I do not understand what is wrong. I have been to multiple therapists, and psychiatrists as well.

Thank you doctor,

I should note that I have been like this since the age of 6 and it is not something recent. I have been prescribed Paxil (SSRI) once and Propranolol (beta blocker) and it actually made me worse. But, I have not tried Ativan, which is a benzodiazepine, and Sizodon, which is an antipsychotic. I believe Ativan could help me a lot but I am a bit hesitant to try Sizodon, to be honest, as I read antipsychotics can cause long-term cognitive impairment. Which is why I wanted to ask you about other forms to reduce anxiety as well and their effectiveness such as Clonidine, anticonvulsants, SNRI, Tricyclic antidepressants, atypical antidepressants, MAOI, and stimulants, which is known to work for some.
