I don't know where I F*cked up !...

Hey man, "Fun" is pretty subjective; even if the whole community push hard on the fact that in order to have fun you have to party, be crazy and so on. You probably don't feel the call from that kind of stuff and it's not bad at all, definitely you had less chances to meet new people but you can also meet people in a thousand different way.
I'm sorry to hear about your parents and i bet it is a huge weight/responsibility you carry on you shoulder. Maybe start low-key, find a few hobbies that you could like and go from there; i would avoid the "300% opposite way" because it could have a price on you, mostly with the smoking part that would be add an addiction to another.
Probably all this discipline will pay you back with the time and you will start to enjoy your life when all the others that had fun will start to look back and regret it.

 

Maybe it is your moral beliefs that are preventing you from interacting with women.

At least in my opinion, women don’t really connect to religious teachings from the Bible or the Koran or other “codes of living”. They seem to be more carefree and just go with the flow of nature. They don’t really think about serious stuff that much, they just do what is necessary to survive.

 

Hey friend, are you in tune with your authentic self?

Who are you? What are your values? What is your purpose in life? What's that you love? Are you in alignment with your true purpose?

Maybe if you find answers to these questions, you'll get more clarity

 

You should get a mohawk and Colt .45 and go to town on the nearest pimp you can find.

 

Now that you are where you have successfully followed your parents ideals for you. It's time to brake free and find your heart and love space. Even if you can take some time off from your job and join a dating club, or etc. I believe you'll be taken right away my friend. There doesn't have to be any connection, you two just connected and all that matters if she's replying back to you. If she's not responsive its a flat tire, dud, out the window. If she keeps talking there is always potential! Then she is one to keep!

Let me tell you something. I dated a Woman back in 2015 and we had literally nothing in common, both a language barrier from Thai to English, silence was in our talks until we became more fluent. Still there was love and commitment, unbreakable attitude towards us. The same can follow and happen to you my friend. Don't feel like you fucked up.

I'd love to be at the spot where you are right now but it's the other way around for me.
I don't want to move up in my job. I see no opportunities.... I don't see myself as a successful job entrepreneur.
