Moving fwd from Grief

I lost my 3 year old grandaughter last june from a brain tumour. Im in a position where I have to make some money in my coaching business as I quit my full time job because it was sucking the life out of me. I only have 1 client at the moment but a shit ton of training.
I just dont feel like I have any energy and everything just feels so hard. I am putting one foot in front of the other each day and moving fwd and I have good days and bad days as the waves of grief come and go but I just want to feel better. Feeling,lost stuck and in fear as I have to put myself out there now to make some moolah. Just dont have the energy. I am 62 but in decent shape. It’s like I dont ven know where to start. Do I start with my eating habits cause Im numbing out on chocolate but then I get panicked cause I need to be figuring out to make some money. Its a hamster wheel…LOL
