can't relate at all - i am a Sperg - i don't even understand how it is possible to feel lonely
i have cut off all my friends about a decade ago, blocked my father's phone and my mother is forbidden from calling me ( though i call her occasionally to say i'm OK )
i never pick up my phone at all - i only check my messages once a day or so.
i mainly just use my phone to listen to Spotify while working out, but i will also call a place to check if it's open before going there etc.
