What you are describing can be due to feeling of being stuck in life.
If you feel you are not spending your day time productively and are just killing time aimlessly for more then 4-5 months. The body might go in automode.
Next Steps
start waking up early by 30 mins.
and stand in morning sun facing the sun and then turn around. for minimum 10 mins.
just do this for atleast 21 days. You will see the magic happen.
2. Increase your water intake with 1 glass of lemon juice once a day.
take this as giving your body a wake up call. So give it sunlight and water. It will wake..
All the best.
