I need help, I think someone died

Edit: before anyone comments something know this; she is homeschooling and uses the laptop with a reddit tab always open, she's not got her own electronics and uses her grandparents laptop, she might be on holiday but I doubt it because it her grandparents r that nice

I started chatting with a random person on reddit and we would text every night until one day she said ttyt (talk to u tmrw)...

She never did I'm worried for her Please help me Idk her real name Ik what she looms like n what state she lives in but im really worried If she has died idk how I'll cope Sorry for the long rant I'm really worried and I need her to talk to again She was the person who truly understood me She was js like me but instead was a girl We spoke about our family problems n listened to eachothers I need serious help Can someone message her n see if she js stopped talking to me cos she didn't like talking to me anymore or if something happened to her I'm hoping she js forgot her login n hs to make a new account

Her account is u/safe_fruit5956 Im worried
