I would say that garnet may be a good stone for you to wear during this time in your life. You are subconsciously drawn to the gemstone.
Nearly every gemstone is "protective" "lucky" "healing" etc. in modern literature. I wouldn't read up on it too much.
Instead, get yourself a garnet, cleanse/bless it, and meditate with it. Let its natural spirit/energy blend with your own and write down your observations.
What it does for you may not be what it does for someone else. Let's take for example two people. Put two people together that "click" and they will fill each other's needs if it is within their capability and when something is actually needed. Gemstones are like friends in this way. They will help you where you need help.
But if you put two people together that clash, they will tear each other down, not because they are bad, but because they are so different or so similar that they bash heads. Again, like people, certain gemstones will not work well with us at all, and may actually hurt us, not because they are bad but because they do not have the synchronicity necessary to make it work.
Work with garnet, but don't get so attached that you do not recognize when you may "grow out of" the friendship. Eventually, a new stone may call to you, because it will be able to help you with a need that is beneficial for you to fill. And it won't fill it for you but instead teach you to fill it for yourself.
