What are the natural interventions that I can use to boost my mental health without going for therapy?

Name: Rina Date of Birth: 11 April 1993 Place of Birth: Guwahati Time: 10:00 AM. Namaste, I've been feeling emotionally down and mentally exhausted for quite some time now. I'm not yet ready to go for therapy, but I want to improve my mental health naturally. I've heard of journaling, herbal teas, and grounding, but I don't know where to start. I'd like to feel more grounded, sleep better, and not think about everything so much. Are there natural remedies or habits that I can do on a daily basis to feel mentally stronger and more centered?
