Is what happened, a touching of the private parts without penetration, considered a grave mistake that warrants this psychological pain and the obsession with the possibility of pregnancy?

This sinful relationship is one of the Devil's steps, from which Allah has warned, and he leads to evil and then sends forth whisperings. Sincere repentance is obligatory, and the relationship with the young man must be severed, and the whisperings repelled by seeking refuge [in Allah] and the remembrance of Allah, for hearts find reassurance in His remembrance. It is unlikely that there is a pregnancy if there was no penetration and the hymen is intact. We hope that what happened will be an impetus for uprightness, obedience to Allah, and the companionship of righteous women, and it is recommended to supplicate frequently for well-being.
