Hello CosmicRose,
Foremost, alcohol will never help to solve any of your problems, it will only make things worse and in the end, you'll only have regrets with zero progress made. Secondly, your family members will never help solve your problems because they also don't understand you completely and also have their own problems to deal with. Third, people will not get you from your current predicament because you understand yourself better than them.

My suggestions:
Seek professional consultation from an expert and explain how you feel about the way you live your life and how/which areas you'd like to see some changes and what changes you think will make your life more enjoyable.

Second suggestion, regarding your economic life, I believe that no one should be stuck in a job that they don't like. To drive that across, what was your hobby while growing up? Do things that you like doing even if the payout is less because people thrive by doing things they're passionate about and that's how new ideas are born, problems solved which in return become more rewarding in multiple ways than they initially thought.

Changing your lonely life:
You said that you've no friends. All of us require great degree of interacting with other people, its how we discover our identities and place in the society. Being social sometimes helps cure things like insecurity, self pity and loneliness. Go out there and meet people whether in a church, local clubs for things that you like and start with baby steps.
