Finding a new therapist but not over my old one?

I recently graduated which means I can no longer see my previous therapist through the school health center. I realize I should have maybe processed how hard it would be ending therapy with her during our last couple sessions, but I never brought it up. I’m pretty sad because I’ve known her for a few years and really grew to trust her. I’m strongly considering not finding a new one because I’m sad about starting therapy with someone new. How can I like them as much as my old therapist? And if I do find a good one, how will I be able to end therapy with them if ending this time around was so hard? Would it be weird to start therapy with someone and first work with them to process leaving my old therapist? I just feel so much resistance towards staring with someone new. Will this pain get easier?
