I have found that doing a guest blog post swap works well. One of my posts appears on another blog with my bio and links back, and I feature one of their posts too. We both gain new followers too as we're in the same blogging niche.
I don't even know what to say after reading this. I feel honoured somehow, that without even knowing you personally, you shared your story with me. I've had so many friends and family members with cancer. Some beat the bastard, others fought as hard as they could but as one them mentioned, "didn't have a big enough stick to beat it with". No matter what anyone tells you, you fight. You fight with everything you have. Whatever approach you chose to go with to fight the bastard, you fight as hard as you can. Sending you much light and strength x
