I am 36 years old unmarried girl. I am having depression, anxiety and stress from last 9 yrs. I feel lethargic all the time. When I wake up in morning after 6-7 hours sleep, I feel lethargic. I sleep for 1 hour after taking tea in morning. After that I do breathing exercise to relax my body and mind. I do meditation for 15-30 mins also. After breathing exercise I feel relaxed and at ease. Is this normal to feel lethargic in morning? I am having lethargy due to depression or stress or lack of sleep or due to poor blood circulation or lack of oxygen in my body? How can I know the reason of having lethargy? Please give me advice.
