High body fat. Kind of hormonal problem?

Hello mam, I am a 18 year old male ,my weight is 70kg. Actually my body is too soft for a 18 year old male ,body is like female body and I have grown some havvy amount of fat over the chest area like man boobs or gyno whatever I don't know. I am very depressed for the matter,do I have some kind of hormonal problem? I do a little research on internet and find out that it may happens because of low testosterone and high estrogen level in body however I am not much aware of this matters. Some people suggest me to lose weight or loss body fat ,so I started some low carb diet and do some lil bit of exercise but that doesn't help me with my problem I only lose some kgs of weight that's all. please mam help me with this matter I want to make sure what kind of problem I have a before a visit. Thanks a lot :)
