Feeling like equals

I need some help with some thinking please. My best friends are considerably more well off than I am. We spend much time together and when we go out they usually pay for everything. I am so grateful to be spending time with them and for their generosity. The problem is the negative chatter in my head that I constantly struggle with. Guilt over them paying vs. not going or spending money we can’t really afford. That is the tip of the iceberg, there are many more layers beneath that. When I do a model it looks like this c: asked out to dinner t: love to go but we shouldn’t spend money on dinner out f:shame,guilt, inadequate a: reluctant behavior r: they offer to buy we eventually accept and I feel the above. I can’t come up with an intentional one that allows me to graciously accept their generosity. I really want to clean this up. Thank you
