If you aren't happy in your current relationship, then break up. If your business partners treat you badly, change them. If your suit doesn't fit you perfectly, give it to someone to wear. You don't sleep well, try to find peace of mind. If you don't feel well, go to a doctor. If you don't like the country you're living in, leave it. Do something, don't (only) whine. Не знаю, возможно ли во всех случаях перевести «плохо» одинаково.
