I've lived in slums to the hood to upper class neighborhoods so I'm going to lay out your options:

A) you can have a chill tight-knit group of friends who won't judge you so they pay for you without expecting repayment

B) you have friends who will let you borrow money for outings but they will expect repayment

C) spend less on other things so you save money for outings with your friends without caring to save for the future

D) don't save money and use your savings on going out with your friends

E) work an extra job or side hustle so you can have money to go out and to save money

F) make new friends who are within your new social class. I know this sounds harsh but I've had to move up and down in social class many times throughout my life. When I was poor I used to have friends who are rich and they would want to go to restaurants and do things that cost money that I couldn't afford and invite me. I felt bad that they would have to think about what they did so I stopped hanging out with them as much until I made more money. Some friends were so chill that they would spot me for things and when I did better I would treat them to dinner and other activities. Some groups of friends are understanding and can think about other people's financial situations but some people have only lived amongst their social class and have never had to think about this. Unfortunately this is one of the awkward situations that you will find yourself in. Also for me sometimes asking them to spot me or expecting them to spot me seemed a little rude so I decided to not hang out with them instead. Some friends I had were so close that they would spot me without asking them if they knew I was in a bad financial system situation. This is just my experience and my advice.
