Feeling fatigued throughout the day.

Respected Doctors, I feel fatigued throughout the day. The feel of fatigueness mostly is in the both sides of the head, palms and feet. Don't want to leave my bed in the morning. Always feel sleepy. Difficulty in concentrating. I also have hypothyroidism and taking thyroxine tab. 50mcg. I Have been taking escitalopram 10mg (reduced the dose to 5mg since last 3 months) from last 1.5 years. Taking Modafinil 100mg from last 10 days. But nothing seems to work. Even just after taking modafinil after breakfast I feel sleepy and go for sleep. Want to know if it will be good for me to switch to homeopathy medicine, because allopathy is not working. Please suggest. Note:- Even now while I'm typing this. I feel like my brain is hijacked by fatigue and telling me to close my eyes and sleep.
