Please I need some advice..

I have been trying my best to get on my feet and follow God's instructions and be with him in every little way... I have been reading the bible walking up at 5 to pray and praying morning and night before heading to bed.. I'm Hispanic so we have some other believes that maybe some of you guys don't believe on. Anyways I made God a promise and i broke that this morning and i feel so bad especially cause I'm scared that God will be mad towards me. Will he forgive me for breaking a promise I made. I really need some advice this is killing me. I don't have no where to turn and I'm embarrassed to just tell God to forgive me cause that's one of the things I tell him every day incase I did something that wasn't write...

Advice please.
