I'm so sick of all the hardwork shit. I need advisory.

I'm not so good with English. Please bear with me. So, I'm 25 F. I have 1 and half year experience in voice process. I'm a very introverted person and doesn't like to talk much. I hated my job moreover at the time of COVID the work pressure was too much to handle and I resigned. Then I joined a company where I'm working under company secretary CS. I have 2 years experience in this company. Currently I'm getting around 20K which I think is too less for my experience. If I'm going to leave the company. I should be atleast a semi qualified CS. I'm going to give my second attempt. I have no motivation to study neither I want to continue in this low paying job. I want to earn enough money. My father is retired. I'm only one earning. It's painful for me to take too much on my own. I want to quit but i got no other option. Please advice me on this. I'm pressurized to earn more money. My sister is still in her college first year. 🙏
