Hi niceguy, it can be so difficult to make a decision when there are lots of different thoughts, feelings, emotions going on. And while you can sometimes trust your feelings at the time (for better or worse- going with the best decision you can make at that time), is there anyway of postponing the decision or just half committing to it/leaving a door open until you've had more time to stand back and think about it or get a bit more feedback/information on how things might go depending on what you decide??
But if not, or I'm out of time replying to this you'll have gone with your instincts, done what you though was right at the time and even if it doesn't turn out so well no-one (not even you!!) can blame you for that.
And don't forget if it doesn't turn out well.......we're/I'm here for you, OK??!!
