Are you posting truly to discuss eidus, or are you asking for help with your sadness? Personally, I am finding that cultivating hakaras hatov as frequently as possible to be a good antidote. Also, I can’t believe that Hashem would create some of us to be more prone to sadness and then would punish us for not always overcoming it, Shabbos or anyday. I find it more helpful to focus on Avinu rather than Malkenu. I’m already good enough at self-flagellation. I don’t think that Hashem would be pleased with my strengthening it.
