Just some advice

"You shouldn't go around fixing people and give up pieces of yourself to make someone else whole

 You can’t be a proper friend to someone, be there to support them, be anything, if you don’t care for yourself first. I speak from experience with this, and it’s a lesson that I have learned the hard way. 

There is nothing noble about thoughtless self-sacrifice.

There is nothing wrong with putting your own needs first, and making sure that you’re okay before you offer anything of yourself.

Giving and giving of yourself only hurts you, and the damage can take a very, very long time to start trying to repair. "

This is actually a mixture of things I have found online from not just one particular author, but I found them all relevant.
