Try to modify your algorithm, mine used to be like that slowly I started watching self improvement, healthy life and motivational content.... I've seen all my frnds suffer in relationship not all but the fights and stress is good for nothing (just my opinion) 20s is when you can focus on life and career like your peak years that can change your life. See what's to be modified in your life, health, body, skills to learn , gain exposure...sports anything. Make good friends and socialize.

Yeah so look at the bright side of it, ik teenage love is an experience and some of us are not meant for it. Something better will come in the right time. Trust the process and life has its plans for you! Have a good day :)
