What can i do if my teeth are horrible what should i do?

Consultation: Have a consultation with a local dentist who can examine you and advise you of your restorative options.

See a dentist: To find out what treatment is necessary in order to have healthy teeth and gums and a bright smile.

Be more specific: What do you mean by horrible? Are they misaligned? Or, discolored? Have missing teeth? Too many cavities? It's hurting? It's sensitive? I bring this up because it is important that you find someone that can address your specific concerns.
