Hi, we can't really tell you whether you have it or not as we're not trained professionals. You seem to relate to a lot of the stuff, on what level I don't know but if you feel you can relate then it is definitely worth seeing someone about it. I am not sure they can tell your parents but as you say being a minor they may, but I really don't know. Possibly speak with them about it first? If you do have a MI, you will need a support system so best to get them on side and give them some understanding.

I wish you the best whatever the case is
