It's very hard to answer a question like this because I'm not in your shoes and I haven't experienced everything that you have experienced.
What I can tell you is that when I'm faced with such a challenge, I will sit quietly each day, thinking about the options at hand, waiting to see if I hear my "inner voice" at all. My intuition is usually a good indicator for me. Sometimes I need to do this for quite awhile (days, weeks, or maybe months) before I get a clear answer.
The best advice I ever got was from a dear friend who warned me to never take action if there is doubt within me. When we make decisions and things don't go the way we think they should, we assume we made the wrong decision. That may not be accurate. I wrote a hub called "Decisions Lead To Action" about this very thing.
I wish you well in whatever choice you make. You will be okay no matter what. We learn from every experience - some lessons are just harder to learn than others.
Blessings to you.
