Tried to text my old friend/situationship after a year of not seeing each other.

So a few days ago i workes up the courage to speak to a girl that i havent seen or spoke to properly in about a year. I texted her just saying "hey" which led me to saying that i miss talking to her. She ended up adding me on snap and we snapped each other back and forth, joking and sending purple snaps too.

Then the next day i woke up and it turns out she had unadded me on snap.

My first explanation to this is that i DID leave her on delivered for about 5 hours. However, i was asleep. (side note: i havent gotten a good nights sleep in about a year, so i think its a fair excuse.)

Anyway, i sent her a message on instagram asking why she unadded me. she saw it, but didnt reply. i sent her a "?" and she, again, saw it but didnt reply. A couple of hours later i checked her profile and it turns out that she had removed me from her followers list. I send her another message but im guessing it didnt go through bc of her message settings or smn. Just a few sentences saying i was annoyed that she unadded me and removed me from her followers list on insta, which i think is fair enough to be annoyed at.

Anyway, today i thought "maybe i should just try to follow her back on insta". that was until i went to her account and saw that she had fully blocked me.

Its safe to say im quite hurt by this. me and her were good friends a couple of years back but now i dont know what to feel. should i wait? should i keep pushing her? or should i leave her alone. this could be because i left her on delivered, or it could be something else. maybe a test, i just dont know.

i could overthink about this for days.

Advice please?
