Am I "lost" in service yet?

Lately, I have been using alot of my time is the service of certain people and I am wondering when am I being of service and when am I being used. I would gladly help anyone I can, and I have actually put others in front of my family to be of service.
We are taught in church at we should lose ourselves in service to our brothers and sisters...well...when is that?
I am ready to pull my hair out due to a perticular person I am really honestly trying to help. I don't want to go into to much detail, but I have been feeling used lately, and I don't like it.
If I stop being helpful will God be disappointed in me..will he think I am not being Christlike?
I just feel like I am ramming my head into the wall and its really fustrating.
I seriously feel that I have to stop and have to put my family ahead of others for a change....that sounds so terrible but I am really really tired of being used!!! I don't think Heavenly Father wanted us to feel that way, right?

learning to be frugal.

Ok, I am learning to be frugal...can you ever go to far? I have been researching different ways to save money and I came across a site or two dealing with making your own pads for "that time of the month". Hmmm....I would love to save money, but can I really do that. I don't know. But I am really thinking of it. ...very seriously.
I made my laundry detergent and its working well, I bake my own bread, and today I decided to make my own marinara sauce instead of buying the jar spaghetti sauce. Are there other ways to save? I don't know how far I can go with this, but I am willing to give everything a try or two. I found a recipe for the shampoo...so I am going to look for the ingredients sometime this week.
I guess I should learn to sew and that might save me lots of money..or will it after I buy the machine?
I will continue to look for different ways to save some money...I actually surfed the web for free samples of shampoo, soap and whatever I can find....love free!!!!!!!!!!!!!
