Am i changing or is there something going on?

[Alex]

First of all, thanks for answering my question, it really helps

Well i am a 15 year old boy and I get this quite alot. It only kicked it about half a year ago on and off. Its nothing major, just growing up. So yes, you are just changing.
A good tip I use is too get out more often. Go to the cinema with friends (or your boyfriend), walk your dog if you have one, just anything to get you up and moving.
