Your personal journey is a lifelong process. Remember that and try your best to meditate on the fact that you have made steps forward, no matter how small they seem.

Vent, complain, air your feelings here, do whatever you can to help yourself in this moment and try not to think about yesterday or tomorrow (very hard at times, I know).

There are good guided meditations on Youtube. A longer one (20-30 minutes) gives you brain time to adjust to focusing and can remove you from a depressed fog, even if it is only temporary.

Best of luck. Imagine your body glowing with a warm golden light around it and tell yourself, "I am love, I am capable, I am everything I need to be right now."
