Dear Friend,
Please get your haemoglobin and Vit D3 levels checked, if they are low take medicines to correct them.
The only way to improve stamina is to do exercise, start slowly, do only as much as you can do easily, slowly increase over period of time. You will need patience for this, but you will definitely get results.
best wishes.
