Where should I start if I want to receive traditional Korean medicine treatment for fatigue accumulation?

Lately, I haven't been feeling well, and I want to receive traditional Korean medicine treatment. Where should I start?

Recently, I have been experiencing increased stress, fatigue, and insomnia frequently. I am curious if there are traditional Korean medicine treatments that can help resolve these symptoms. I started studying, and suddenly my physical condition worsened. I had a check-up at the hospital just in case, but they said there were no significant issues and that it might just be due to stress. Due to lingering fatigue and minor illnesses, I am unable to carry out my daily activities properly.

My biggest concerns are frequent gastritis, indigestion, irritable bowel syndrome, and frequent colds. I also feel like my immune system is generally weakened.

Thank you in advance for your response.
