Popa- I beg to defer. Because you resent it doesn,t mean you shouldn’t do it, it means you need to work on yourself. What’s if you resent giving maaser from your hard earned money. Are you patur?
“If you are ignoring your own needs, you are a pushover.”
You don’t have to ignore your needs- you need to redefine your priorities. You need to help another Jew because H-shem wants you to regardless of whether they shower you with gratitude or not.
