Feeling overwhelmed by constant stress—how do you find calm?

Lately, it feels like every little thing adds up and my mind just won’t quiet down. This has been creeping up on me for a few months now, but it’s really gotten worse in the last couple of weeks. I find myself lying awake at night, replaying conversations or stressing about things that haven’t even happened. Even simple tasks feel heavier and more exhausting. I try to take breaks and do things I enjoy, like reading or going for a walk, but the relief doesn’t last long. It’s frustrating because I want to feel more in control, but instead, I just spiral into this fog of anxiety and tension. I’m hoping to hear from others who’ve been through similar waves of stress—how do you manage when it feels overwhelming? Are there small habits or shifts that have helped you find a bit of calm during tough times?
