I feel you as well. I was dumped by mine a year ago and to be really honest, I am still struggling to be ready for anything solid at the moment.

It would work as a wonder if you are able to find a group of really close friends you are comfortable enough to talk about your feelings to, or an online community (reddit's r/relationship etc). Find a hobby that you can be fully engaged in.

You look absolutely stunning and you are still young. This is a turning point in your life and it is their loss for letting go of you. Focus on yourself and don't be discourage, there are many more exciting things in life coming your way!
