It's definitely a burden. But if there's shadow, there's light. It's best to focus on what brings joy in my life.
Problem with people and problem with studies is completely different. I don't need shits from people to waste my time, i have better and worthy things to care than them. So yes, sadness had been overwhelmed my life lately. But doesn't mean i'm out of happiness in my other hand. The only way i can bear this is by looking at the bright side where i can see the light and ignore those eerie shadows behind me that constantly try to eat me up.
