The phone numbers of people that never, ever call you or text you first, and often don’t even respond when you text them. Mean or uncomfortable exchanges with people — either in your text or internet history — that you occasionally go over and re-read because they make you feel angry and terrible all over again. Subscriptions to online stores that you can’t afford, and which send you tons of emails and texts about the sales you should not be spending money on. Bitterness over the things that your friends or coworkers have, that you might not be able to afford or have time for. Expectations about having “the perfect” significant other, or someone who is going to make you feel better about yourself/fix your problems in a way you’re not able to do on your own.
