Most people have less than you think. You can't determine a person's net worth by the car they drive, the house they live in, or how much money they're showing on social media.
The average millionaire lives a very modest and frugal life. The people that tend to brag about their money are usually great earners but terrible money managers. These people look wealthy, but in reality or very financially poor.
You're going to do yourself a disservice comparing yourself to something that's not real. Don't keep up with the Joneses. Find out who you are and what you value. Being rich is subjective. Your rich life is your version of rich.
That's why I tell myself I'm rich every day. I know what matters to me, and I'm living the life that I want to live. Once you find that, the pressures of life begin to loosing up.
That's when you start living instead of surviving.
