Can i get braces if its really hard for me to chew food and my toungh sticks out (pushes my teeth) and i have a gap between my upper and under teeth??

Yes, but.....: Braces may not solve your problem. First you need to address the tongue thrust habit. Your tongue is causing the problem, not your teeth. Presuming you did correct your teeth with braces, as soon as they came off your tongue would push the teeth back out again. You need to see a qualified speech therapist for myofunctional therapy before having braces placed.

Of course: There are three main reasons why people seek orthodontic treatment: proper function (chewing), improve the esthetics (close gaps) and improve oral and general health. You should visit a qualified Orthodontist for consultation.

Yes: You will probably need to wear a removable appliance which will train your tongue thrusting habit to relax the tongue and have to close your teeth together comfortably.
