This kind of situation is very common but we all can agree that it's hard to manage your finances if you're a low or middle wage earner. Especially nowadays where basic needs and everything is getting more expensive due to inflation. But if you really have a strong mindset when it comes to budgeting, you can allocate your income properly. Also, I'd suggest to find other sources of income since if you know that your salary isn't enough, you can't just settle for that.
It's not easy but knowing your priorities and having self control with how you spend your money is a great attitude in order to manage your finances properly. Also, always try to look for an opportunity (even if it's a small one) on things or events around you. It might help with your income and finances.
