There are people who suffer but there are some who are self absorbed and think they are the only ones.
If you think about it most people will experience their loved ones dying and everyone will experience death. For some reason, some people feel entitled to abuse others in workplaces, friendships, relationships etc. So you just have to steer clear but that is hard. Allah tests everyone. If you can avoid abusive people, try your best.
Also social media has jaded people and has led to unrealistic expectations about life. Imo surrounding yourself with good people is crucial to not end up jaded and cynical. And remeber everything is temporary including pain and happiness. This is a blessing. Thats what helped me and accepting things that I cannot control.
