If you're low on money, don't buy expensive pizza. Maybe that's why you can't afford it on your own?
0.0035BTC is ~22 USD, which should be able to buy around 5 frozen pizzas in the USA, or 2-3 pizzas from a restaurant. If you're in a third world country, it should be even cheaper. I would reconsider your spending habits to avoid this situation in the future; if you lack income, become more frugal instead of trying to live a rich lifestyle.
here 2 large pizza cost around $17 but anyway thanks for advice now closing this topic
