<human>: Can you condense the text into a few key points?

I just got dumped again from what I now realize was yet another toxic relationship (2 yrs). I allowed it to take over my life to the point of negatively affecting my friendships, mental health, and grades. Most embarrassingly, I didn't look for jobs yet even though I just graduated because I wanted to wait for him to decide which city we wanted to move to, so now I also don't have a job or a plan except my shitty part-time job and it's already June. I am frantically trying to get my shit together now, but I am still reeling from heartbreak and I find it difficult although I know I need to take action.

In retrospect, I now realize that I consistently make bad choices in relationships to always be the one sacrificing more. Or to allow relationship drama to completely overtake my life to the point of affecting my work ethic, time for hobbies or friends, etc. I would like to learn to make myself, rather than the people I date, my top priority. And to take responsibility to not end up in situations like this again. Any success stories to give me hope or strategy?
<bot>: If you have previously been the kind of person to prioritize your SO or spend so much energy on relationship drama as to fuck yourself over, how did you learn to make yourself your top priority? I want to learn.
