What you can do in between those things is to use your own hands and make yourself busy. Playing video games or watching shows and movies would be nice, but sometimes, it can get a little too boring after a while.
It's just that you would need to find ways on how to get entertained just by yourself. Being alone doesn't mean that it's the end of the world. Maybe it's because of all those ways and options that actually made us feel more alone in the first place? And in this case, the only person we can rely on is ourselves. Feeling lonely and alone, with no one to stand by you right now? It's a pretty common occurrence, even if in this day and age, it's easier than ever to get in touch with anyone and everyone you want to.
