Working out did not help with my mental health

I started working out around 3-4 months ago, for my mental health's sake. And let me tell you guys something, I think I am in a worse mental health scenario. I lost some weight, put on some muscles on my chest and biceps, but my mood got worse because my body is tired all the time. I have a good sleeping schedule, and everyday I take good amount of calories and proteins. What would help?
