You don’t deserve to be in the space where you are not appreciated.
It’s good that someone who didn’t value you left.
Now only focus on yourself, have a sense of independence.
Focus on a goal, give yourself some time to heal.
Don’t rush or don’t make an opinion about yourself that you are not good enough. You are your best version.
