:wave: Hi Deckylan,
I think sleeping with your handphone under your pillow for three months would not cause memory loss. Negative effects from handphones are rare and would take years of almost constant exposure.
Short term memory loss in a young person might come from stress, anxiety, hormonal changes, preoccupation with social activities, drug use or cigarette smoking.
Prescription medications can effect memory too.
You should tell your folks the difficulties you've been having. Perhaps a routine check with your doctor can put your mind at ease.
