The best advice I can give is to say I never give advice. I share my experience in hope that it will work for others, too.
I’ve found that people rarely follow advice, but if they can see that I have been in a similar situation and that I found a way out, they will listen to what I say and often follow it.
Learn to take care of yourself. If you rely on somebody else to take care of you, you are screwed on that day that they decide not to, because you can’t force them to do it forever.
