Question from someone with depression

I'm a patient with moderate to mild depression. Lately, I've been feeling anxious due to exam preparations, and I'm having trouble sleeping or I'm having constant dreams after falling asleep. Do you have any suggestions? I usually exercise about once every 2-3 days. Before, to relax, I used to play TFT for a bit before bed to focus on the game and not think about other things, then lie down to sleep after 1-2 matches. Thank you, everyone. Whether it helps me or not, Thank you all for your suggestions. I'll give a small tip to show my appreciation.
