Always avoid opening your mouth for the satan. 
   This quote is from Brochos 19 a , 6 lines up. 
   If a person says negative things about himself it is a form of accepting the possibility rather than praying to Hashem for help to avoid problems. A person should pray for Hashems assisstance to become righteous , repentant & healthy. 
    You can say , Hashem please help me feel well , please help me learn more , pray better & help others more. 
    Speak of what you want. Think positive & speak positive & Hashem can help it happen. 
    When we serve Hashem always with Joy , He can make it even better. Baruch Hashem
