I used to be very skinny but I suffers from a deep depression for a while and gained 20 pounds over the summer so now I'm wondering if this is an unhealthy weight?

Hi! Have you tried figuring out your bmi? Body mass index. It gives you a rough idea of where you are at regarding a healthy weight for your age and height. But remember sweetie, health is more than weight. You can be 141 pound of pure fat, or 141 of rippling tight muscles.

You can consult a doctor to find your cholesterol or blood pressure or that good stuff, but as long as you are not obese, you could be fine :)

You are fine.

Underweight = <18.5
Normal weight = 18.5–24.9
Overweight = 25–29.9
Obesity = BMI of 30 or greater

Your BMI is 22.
