The emotional pain. When you discover that someone you love has cheated, it feels like your heart is being ripped out. You feel betrayed, angry, sad, and confused all at once. For example, a friend of mine found out her boyfriend was cheating. She cried for days and couldn't eat or sleep properly. It took her a long time to even start to feel normal again. The emotional damage can be long - lasting and very difficult to overcome.
For me, the worst part is the aftermath. After finding out about the cheating, there are so many decisions to make. Do you forgive? Do you leave? And if you forgive, how do you ever forget? There's also the public aspect if people know. You might feel ashamed or embarrassed. In my case, when my sister's partner cheated, she had to deal with family members asking questions and giving advice, which just added to her stress.
The broken trust. Once you find out someone has cheated, it's hard to trust them or anyone else again in the same way.
The lack of respect for personal space is the worst. For example, if a roommate constantly barges into your room without knocking or uses your personal items without permission.
In my experience, the most horrible part of jury duty was the nature of the case. I had to listen to really tragic and disturbing details. It haunted me for a long time after the trial was over. I couldn't get those images and stories out of my head.
The worst part could be the disruption of peace. For example, if you are in a quiet place like a library garden, and suddenly the quadcopter noise invades. It shatters the calmness and tranquility that you were enjoying.
Allergic reactions are the worst. When your eyes swell up and become itchy and red, it's not only painful but also a health risk. It can also be really inconvenient as you need to seek medical help, take medications, and you can't just ignore it. Plus, it means you have wasted your money on the lash extensions that you can't even keep on your eyes.
The worst part could be feeling completely alone and lost. Like when you're new and no one seems to care or help you. It's a horrible feeling in a strange new environment.
The worst part is probably the embarrassment. You don't want others to know and you're constantly worried about any signs showing. It's that feeling of being exposed.
For me, it would be finding out that the person you're on a date with is completely different from what they presented themselves as online. Maybe they used old pictures or lied about their job or interests. It just makes you feel deceived.
The worst part could be getting a completely inedible meal. Maybe it was spoiled during delivery, or the restaurant prepared it very poorly. It's such a waste of money and really disappointing.
The worst part could be bad breath. I mean, when you are expecting a sweet first kiss and then you get a whiff of something really unpleasant, it just kills the mood instantly.
I once had a friend who was in a relationship. Her partner cheated on her. She found out when she saw flirty messages on his phone from another girl. She was devastated. It completely broke her trust in relationships for a long time.
