I've been lying to people that I have money and now it's biting me in the ass

For the longest time I've been lying to people that I always have the money to do things. To them I have always been known as someone who always has money. I often would offer the buy our whole hang out food, or go out to an arcade, always stop by the store to pick something out. This is all far from the truth. I don't actually have a lot of money, I've always been a big spender and it's been a big problem for me. I spend so much on people I am with because for some reason I feel guilt that they are around me. Like I owe them for spending time with me. I have a lot of friends that care about me a lot, they're seeing me at a down and are willing to help but I can't help but feel terrible. I've been wanting to spend on people so much and now I can only eat a meal at night and wake up with regret that I spend all my money recklessly because I wanted to shower the people I cared for. I don't regret being with them or spending the money on them, I regret just how much I spent and how now I'm stuck without anything.
