You aren't emotionally unstable. You were upset and that's not unique reaction to a break up especially at your age. As we get older we become more philosophical and we realize deep inside that breaking up happens for a reason and more often than not the person was wrong for us.

At 17 thought it feels like end of the world coming. Like she is the love of your life etc

Now as the time passes you start feeling better, that's normal. You might feel upset again etc it could go in cycles.

You are going through grieving and everyone does it differently and it is normal. There is nothing wrong with you. We all been there. We all had first gf or bf etc

You will be fine. You have a great future and I know you'll meet some great woman in the future.
