That's a hell of a schedule. I'm assuming you're a young guy since just reading your weekly workload made my middle-aged knees hurt.
You have zero rest days to work with, and you're already down to a 2-day program, so I think your best bet is to address the food issue. I don't think you mentioned your height, but if you're a volleyball player, 85kg is probably pretty thin.
Bottom line: you need to eat more. If you're constantly feeling beat up and you're getting good sleep, then food is the problem. Bump your calories up and focus on adding more protein. Work with what you're already doing. If you have rice with your dinner, add a second serving. If you have one scoop of whey for your protein shake, make it a two-scooper, or try adding a second or third shake. Just humor me for the next few weeks and try to gain 1/2 - 1lb per week. My guess is that raising your caloric intake will help you recover from all this activity, and you'll feel a lot better. Your lifts may even feel a little lighter. Keep us posted.
