depression . natural remedies please help?

im depressed. for no reason really.!! well like im having problems with my boyfriend not major problems but hes just not as perfect as he used to be and i do blame myself. dumping him is not an option as it would make me sprial into a deeper depression i love him alot!! im very dependent on him though and i think this is my problem. i want to be a stronger women. first i need to get rid of my depression. my doctor advised me away from anti depressents bcuz they are addictive . is there any natural remedies?
