I'm a guy, I'm pansexual, why?
i just wanted to make sure i understood.
i don't know what to tell you. romance and stopping romance is a lot like being addicted to a drug and then stopping...
it hurts like hell, you have to go COLD TURKEY or it won't work.
no calls, no photos, block on social media completely, no talking with any close friends of theirs who will mention them
first 3 weeks are hardest, feels like absolute shit, after 3 weeks, it goes from extreme pain to awful pain, and you have to get through next 3 months depressed, after 3 months of depression, the next 3 you may just feel flat or mildly bad, just don't make the mistake of going back and contacting them, it's like an addict having a drug again, it will restart the entire clock.
6 months, no contact at all, not online, not talking, not anything, and it will start to get slightly normal again. but you can't see them, hear them, anything. delete photos, delete social media, move on
if this person loved you, they would probably be with you. and really, you're 19, you're probably hot (or i envision you that way, despite not knowing you), probably a lot of guys would want to be with you... just chill, wait for 6 months to pass, you'll find someone else if you can sort out your mental health stuff enough to be cool.
(i'm super old and not hitting on you. you wouldn't be interested, trust; just trying to let you know that time and zero contact will help you deal with this)
also sorry if this isn't what you want to hear. i remember your first post and i know you're so depressed at times i'm scared to reply, hope i don't say the wrong things to you... hope this doesn't make it worse somehow.
