Overwhelmed

So much lately I have been overwhelmed.
Mainly because its my fault:

I like to help people. So what do I do. Help them. Even when it causes a sacrifice on my part. Which is more than ok. Most of the time at least.
Why do I say Yes, Ok, when I am already full of things to do and obligations?
Why do I continue to allow my self to be pulled in by the lull of helping people, when I know I don't think I can fulfill it.
Though I don't think that at the time, I usually think "oh I will get it done somehow"
Though somehow, doesn't really result in the reality of things.

I like that I like to help people, though sometimes I wish I didn't care so much. ..
