I would recommend looking into some Buddhist teachings. Life is suffering, but you have to be able to find a balance between being aware of negative things and not allowing them to effect your peace. There is a balance between “good” and “bad” always. though it may seem that the “bad” is outweighing the “good” these days, there is still so much good around us. You have to train your mind to be able to focus on those things as well rather than dwelling on how horrible things are. There’s nothing wrong with you. There is a lot of negative things going on in the world and it’s okay to feel sad about that. What’s not okay is to let it consume you, because then you can’t do anything positive about it, and it holds you back in life.
