Chess/ depression

This past year is probably the worst year of my life,I've lost 2 family members in the same month and week, I have gotten seriously depressed (like not willing to go out with friends ,study,have fun,eat ). I thought playing chess was the only think that kept me somewhat sane,but as of today, I realized that even chess,something I love, seems to be incredibly difficult for me.The point is,I suck,no matter how many youtube videos I watch or how many games analyzed, I just can't improve,it's always the same blunders,or strategic error that keeps me from improving. Getting to 900 made me happy,only to found out that I lack skills to be 900.So the point is,is my depression/tough year keeping me from improving? Or am I really that bad, that even if I ha a perfect year I wouldn't improve?

Please I beg you,if you can help me out, saying anything to either cheer m up or to strengthen my point of view will he greatly appreciated. But please don't ignore me,just say hi you such or hi keep trying will be enough.

Então @igor_Teixeira, talvez você não esteja estudando xadrez da forma correta, por exemplo, não adianta fazer um monte de puzzles se você não calcular com calma o melhor o lance, eu tava vendo seu histórico de puzzle rush e você joga muito rápido, não demora nem 1 minuto em cada puzzle, daí não adianta (tenta calcular no mínimo 3 minutos por puzzle)

E tem que fazer puzzles todos os dias se você quiser melhorar (de preferência faça antes de começar jogar).

Look, no problem! We've all been there! If not all, almost! And the ones that won't be soon! I know I'm not a very experienced person, but one thing you can be sure of: I have life experience! Much! I've been there. But in different ways. I asked myself: Why? Why do we exist? When we disappear, it's as if we never existed. We won't even be able to remember what happened! I could never imagine a world without me, and neither is it. I realized, with a lot of help, why... You get it, problems. But it passed. Of course I still have them, they haunt me many times, I don't feel like anything, but that's life, I've learned not to think about them. Why? I always thought that when I was about to disappear from this world I would understand, but now I understand that I will never understand! So, better this than nothing, isn't it?
