Underweight but I feel finešŸ¤”

Iā€™m 5ā€™5 and about 96-100 pounds (it varies) and I feel perfectly healthy. I have an extremely hard time gaining it, Iā€™ve tried for the past year with different diets, and even just eating tonnnsss. I look too skinny which I donā€™t like, Iā€™m very self conscious about it, but overall Iā€™m healthy. I donā€™t feel sick at all, and I have a good appetite. Do you guys think I should continue different diets, or just eat and let my body do itā€™s own thing?šŸ¤·ā€ā™€ļø Iā€™m not really sure what to do anymore.
