Hi Friend2U...
First of all..what a beautiful name.

Sounds like you are a really good friend and caring human being.

Your post is revealing. You use strong language when you say "literally break your back" for others.

I think this likely means that you have hurt yourself helping another and to make matters WORSE this other person doesn't seem to care or appreciate at all your efforts.

The bible says...love one another AS WE LOVE OURSELVES. (I'm paraphrasing).

The problem is that sometimes we forget that second part.

It is not a loving thing to do to hurt ourselves (to break our backs).

So, if you can help another without hurting yourself...then you might chose to do this sometimes. AND of course if your helping someone who is appreciative and/or who will help you in kind, you might very well chose to help them more often!

Life is often a matter of trial and error. If you are sitting back reviewing this situation and realized it wasn't worth it....that's kind of a good thing.

Sure it stings for the moment. Let it be a moment. A moment in time.

Now, its time to make a correction.

This felt crummy. This wasn't worth it. No, breaking your back for someone else isn't worth it and this goes double if the person is not appreciative, etc.

So, I hope that you can move forward, realize that you must be a kind soul to want to help another in the first place and just make a choice to never hurt yourself when helping others and seek friendships with those who are appreciative and kind (like yourself).
