Low mood. Don't feel like doing anythn.

I have pain and low energy in whloe body. Pain in feet persist for 24 hours since 2 years hence suffering from low mood and unknown fear. Don't take any initiative also and just stay at home. Tried nexito 10 & 20mg, prothiaden 75 and clonazepam. Now I'm taking GB 29 Total (pregabalin75mg, nortriptyline 10mg plus methylcobalamin 1500 mg). I thought to increase nortriptyline a little but couldn't find it separately. Feel sleepy and tired in the daytime which TROUBLES ME THE MOST due to this can't do anything. So I keep experimenting with medicines but none worked. My other test, lipid profile are fine... Just have thyroid sph 4.2. What Medicine can help me? Or how to increase nortriptyline a little to see if it works? Thanks
