I can't tell you it'll all be okay, because I don't know that. But I wish I did, I've been going through the same thing and those waves of sadness get worse when I'm alone at night. It's a horrible feeling and I understand you. All I can say is that, if you ever feel the need to or if things get too hard, don't hesitate to seek professional help. As for me, I can't do that bcuz I would have to talk to my parents abt it and I don't want that to happen but if you can, please do it. Your mental health is as important as your physical health! And if you ever need smn to talk to, my dms are always open ♡
Things may be hard now, but one day, you'll be fine again. Please take care of yourself ❤
