If your request is truly reasonable, go ahead and ask. If you refrain, you might end up feeling a sense of self-resentment that's really unhealthy. Asking for help, whether it's a donation or crashing at someone's place, is a beautiful thing. When people like you, they genuinely want to help. Them helping is a great opportunity to strengthen your relationship with someone. People are often so happy to help. It can be intimidating to face rejection, but if you're never getting rejected, you might not be asking frequently enough. Asking for things is normal and good, so don't be afraid!
