I can understand your concern.
You may be malnourished in the category of undernourishment.
Also having anemia and other micronutrient deficiency.
Take a high protein diet, have lots of greens and fruits. Have a high calorie diet at regular intervals. Along with having 3 full meals, have 3 smaller meals consisting of fruits and vegetables.
Have one or two eggs daily, take livogen-z once a day, tab. Shelcal HD once a day, tab. D3 must 60k to be chewed once every alternate day for a month.
Take one tablet albendazole before bed for 1 day for de-worming.
Get your basic blood investigations done and consult a general physician for further help.

Hi there . Your symptoms may be due to under nourishment. Have sprouts, protein shakes, milk shakes, have vegetables like (potatoes, peas, corn, carrots, winter squash, beets), have fruits like (bananas, pears, apples, pineapple, dried fruit) , if your non vegetarian then have one egg everyday, have chicken and meat atleast twice a week. Have milk and diary products. You can have protein supplements, many protein powders are available in market, mix with milk and have them twice/thrice daily, have more calcium rich foods.. do weight training exercises, gyming ( it helps your muscle mass to increase and help you gain weight and even increases your appetite and even increase your stamina) hope this helps you. Consult dietician once.
