Where do you draw the line ?

Sometimes you start to wonder, where do you draw the line when it comes to helping someone?

When someone (of course I'm referring to people whom I care about i.e. family, close friends) is in need, its just natural that I want to help. I'm generally a super passive person, I dunno how to help but I'll step in to do what I can if I've been asked. This time I know I have to step in to help, and initial intention is to do whatever I can to help. But while waiting for the situation to clear so that we all know how to help, I start to have my doubts.

• How much can I do for them ?
• Will doing this help much ?
• Whatever I need to do to help will have implication (everything is above the law here pls :P) on me too. Am I prepared for it ? Am I subjecting myself to unnecessary vulnerability ?
  
• Will I become resentful in future for doing what I did ?
  

I feel selfish for thinking about MYSELF when someone is in need and I'm suppose to be doing what I can to help. That's what prompted my little brain to keep asking, where/how do I draw the line ?

As an outsider, I always say "Just help in whatever you can, within your means". I still live by this mantra, but the question now is "What is within my means" ? "Where is my threshold or boundaries?"

Kinda OD on these tots right now ..... got to clear my head and I can't go running!
