I have an overbite, weak chin, long nose. Am I a candidate for rhinoplasty/chin implant and corrective jaw surgery? (Photo)

Being an option, chin implants have serious disadvantages, specially in
the mid and long term, patients are rarely happy with them after 5-6
years, all are out by then or later.Consider the chin advancement by means of sliding genioplasty, the advantages are:-lifetime procedure, no more revision or renewal procedures-more natural than implants-no visibility of implant edges during gestures-improves
the double chin effect at the sub-mental muscles (floor of mouth)
hammock caused by lack of tension there; also improves the shape and
tension of perioral muscles; implants do no offer this feature-horse-shoe enhancement, covering the chin and also the jaw sides of it-no future displacements or neuritis of mental nerves-practically zero infections and 100% healing of bones-no
need for complex plates and screws that may need future removal; just
steel wires synthesis may suffice, they stay buried into bone callusThe cons are:-expensive, but cheap if you consider the lifetime pros-technically
demanding, few surgeons are experienced or comfortable (though I
personally perform 100% of the chin augmentations by this osseous
method, always after offering the patients both options)-scary for the patient (though not so much if you explain well the stuff around it)I don't see reasons for jaw surgery. Your rhinoplasty is indicated, a profile plasty (nose + chin) is the best option for you. But please, do wait until you are at least 19-20.

At your young age with a malocclusion, you need to consider a jaw surgery evaluation. At the least you need a sliding genioplasty but lower jaw advancement surgery should be initially investigated. A rhinoplasty can be performed before, during or after jaw surgery. 

The photographs demonstrate an overly projecting nose,  and an under projecting chin. The rhinoplasty procedure can be performed with closed rhinoplasty techniques to reduce the projection, narrow and straighten the nasal bones after being fractured.  A chin implant can be inserted through a sub mental approach to give added projection to the chin to help with facial balance and proportions. For many examples and more information, please see the video and  the link below

From the photos that you submitted, it does appear that you would benefit from a rhinoplasty in addition to a chin implant. This will create more harmony with the facial structures/features. Without seeing how your teeth come together, it is difficult to determine your occlusion and if you would require any corrective jaw surgery. If your occlusion is normal, you will likely only need to address your concerns with a chin implant and rhinoplasty. I recommend scheduling a consultation with a rhinoplasty specialist to get a thorough examination. 

I am sorry you are bullied...you are a very  handsome young man.  Yes, you do have a bit of a weak chin which can easily be corrected with an implant or even filler to project the chin forward.  Adding this projection will give better balance to the lower half of your face.  Yes, a rhinoplasty can help define the nose better.  Adding angularity to your face can easily be done through implants and/or surgery.  See the link below to see how just adding a bit of filler can give you a more angular face.
