It's not all negative. You may have to dig a little. Unfortunately this is a community of people mourning silence. With that comes alot of negativity. I generally try and be positive but some days it's cathartic just to complain. We suffer together to not feel alone.
Negative Bias. We have a tendency to give more importance to negative experiences rather than positive or even neutral experiences. The mind dwells on negativity.
Try your best not to immerse yourself in the negativity, especially if you're a newcomer. You don't need to see that right now. Remember the negativity is not showing the bigger picture here.
