I want to share my favorite fic of how Tech was fine... it is by Annonymus_07 on Ao3.
He had some help to be okay and get back to his brothers <3 https://archiveofourown.org/works/65188726/chapters/167678035

Summary: Tech was still alive. Why? Sacrifice always comes at a price. But it seemed that price was already paid it. Hurt, with no idea how to get back to his squad or who this special girl was who, oddly enough, found him fascinating; he had only one resolution in his heart: to ensure his own safety, the girl's, and tell his brothers about the situation he was involved in. Although, for the first time in his short and complicated life, he still didn't know how.
