Doesn't matter where you live or where you are in life, nobody became successful overnight unless they were lucky enough or born to a wealthy family or win the lottery, which is unlikely for most people.
Nobody became successful from a business man to a professional fighter without having to spend 'years' of training, failing, f***ing up and experiencing things. Never be upset about failing or losing in life as such experiences offer very valuable lessons in life. Failing does hurt at times but that's how you learn a lesson. Not trying and sitting there while time passes also hurts. Trying and failing is better than sitting there wondering why I didnt talk to this girl or I didnt take the right choice. How successful you are, how much money you have or how many women want you, is no measurement to what kind of person you are of want to be.
Many people out there, especially in middle eastern and central asian societies, are insecure and actually chose to live life that way becoming nothing more but a bunch of judgmental morons who get jealous if somebody is better than them.. Even some of them go to the extent of harming or crushing somebody that might seem to be smarter or better or different from the rest of the cattle. They also do the usual: "buying stuff they dont need, to impress people they dont like, by using money they dont have".
Plus bullies target insecure people because they seriously got issues themselves. No person is a sane person if he wants to hurt somebody because they get an enjoyment out of it, this person got issues and look for vulnerable targets to pick on and vent their frustration on. They deserve a f*** in th*** a** but one must be the better person to learn that these people, their opinions and attitudes should not affect your decisions in life.
A secure and mature person doesn't give a crap about those morons and will chose to assertively deal with them without caring about what anybody would think of his actions or decisions. Rather you should be the better person that positively influences people.. Plus if somebody doesn't like you, then most you shouldn't give a shit about their opinions or thoughts.. Having little to no friends is better than hanging out with a bunch of people that put you down or to run behind people & seek their approval for the sake of getting more friends. Never do things because others do so or tell you to do so, rather do what you find is right for you and only for you.
You just need to take care of yourself and make sure you build yourself to the person you wish to be.. You need to learn that you went through a bad experience that might have mentally scarred you and is not easy to get over with yet one should work to slowly heal themselves.. 'Love yourself more than anybody else but also love your loved ones whether they are your family or wife or close friends as much as you love yourself..
Do stuff that is emotionally compelling to you, surround yourself by people who encourage you to become better and influence you to do good things, get a job in something you like, take care of your physical and mental health by exercising and 'eating healthy'. Study and learn ways to overcome an understand your fear.
The key is to do things that improve your life and slowly allow you to get over your fears and anxiety.. Nobody lives without fear or anxiety but some people have a higher level due to past experiences or are are brought up that way.
Successful people are not the ones with money and fame as most idiots think, rather the ones that endure the crazy things life throws at them and walk out of it with their heads held up high. Some people lost their families to war or disease, lost entire careers or wealth and chose to keep fighting as they know that giving up never gets us anywhere.
Example: Steve Jobs lost his business and got bankrupt in the 90s, can you imagine how it felt for him? He didnt give up rather he started his own computer company, called Next along with Pixar and a few other companies.. Until Apple begged him to come back.
We live in a very random and crazy world that we cannot change or control, the only way to shape it is by working on building ourselves, learning and experiencing new things that add to our understanding and knowledge about ourselves, others and the world.
