Need some genuine help

Hey Redditors

I'm sure this might sound foolish and embarrassing for me, but I need your help. Please do read.

So I come from tier 3 city and currently working in Mumbai as CA, living with my family. I earn elementary and enjoy my work. Now the issue is I cannot spend a penny out of it.

My parents make me feel guilty about spending bare minimum of it. I do not have any friends here, so I just sit at home if ever I get some time out of work. I dont have any fascination of something, no relationship, no addiction. The bare minimum I need is for my commute and some essentials. It may be around 3-4k monthly. Having said that I just don't want to go and ask them for money. Nor do I want to explain them why I spent it if they clearly know why i did it, if I spend without them knowing.

All of my salary is credited to bank and I have no means to use it. Can you guys share me tips on how can I do some extra parttime work and earn that doesn't go in my bank. For context, I already work full time so working somewhere late or early doesn't work for me. I just want to earn so I can afford my commute and some extra. Also if it is remote, it will anyways be credited in bank, which again is of no use. I have no friends so I cannot use someone's account neither I can open another account in my name because that will anyway be revealed one day and I cannot bear the consequences.

I may sound terrible and foolish but needed your help. Please do not ask me to be bold and that, because I have done all that and it turns out to be a nightmare and emotional torture again and again.
