What can I do when I'm bored at home all summer with no friends?

I can take a nice long bath to relax and concentrate on myself for a while. I could also read a novel to calm myself down with all the summer stress. Books are amazing way to destress myself because I tend to find words I don't know yet that I like to practice spelling. My friend Julia also suggested taking a bath in Epsom salts because that is what she did when we had five tests in one school week and she was so stressed and after she got the bath in the Epsom salts she was not stressed and got 100% on all 5.

Read, write a story or a poem, dance to some music, sing, watch tv, watch movies, tv shows, write in your journal if you have one, take some pictures, paint, macrame, cook, go for a walk, when you are alone it can help you clear your mind, workout, yoga, meditation, watch a documentary, play with your sibligs, spend time with them if you have them, watch a video on youtube, be on social media. Those are all the things i like to do in my free time. As an introvert it is very easy for me to find something to do. But i undersand people who don't really like to stay home all summer
