@nin99Do you have addiction to alcohol or drugs?
I'll try to work your problem out use my current best ability in metaphysics
why fall like nobody în 2019 2020 2021.
I am not very happy about my life
Your source of unhappiness in life is very likely cause by your relationship with other people. You like socializing and Relationship with other people is important to you, but other people in your life often dissapoint you. Friends are the number 1 toxic people in your chart, so you better be careful with whom you trust. In Bazi, your month pillar (Ren Zi) is problematic. You have better luck with female friends than male friends.
Do you have dog as pet? If not, consider having one to mitigate your stress in relationship. Golden Retriever can be a good choice, this species is very smart, big, sociable (it get stress without human or other dog as friends)

Your father is helpful for you despite his spicy words and behavior. Maybe try to
tolerate him and be more open up to him? Convince him that you can't follow "his way" after you did your best to follow "his way"?
As of 2019, 2020, 2021 being bad year. that's because water & metal are bad for your chart. Either you lose money or got betrayal.
For your career choice, I don't think you're suit to become a doctor or in pharmacy. Your chart doesn't show good healing ability, and you also have communication problem and difficulty to understand people. But being in dermatology isn't a bad choice, I do think you are better on cosmetic surgery, doing beauty treatment like laser, having beauty clinic and selling skin care cream to woman.
when I will be powerful again
Too exhausting to check year by year, so by quick glance: 2038 Wu Wu year.
Probably this would be your best year to gain respect and power. Wu Wu year also fall into Bing Wu LP. But you need to be careful not to use too much money to exert power
Your ZWDS Wu (horse) palace has many good stars, so Wu year often become good year for you
