The old saying is “What doesn’t kill you makes you stronger”. I don’t know exactly what you went through or going through, but your attitude towards it is fantastic. Stay positive my dear friend. When my dad was diagnosed in 1998 with cancer he fought his ass off, he had plenty of really hard days. But somehow he pulled through them. He got through the worst of it and managed to get 18 quality years afterwards.
My thoughts and prayers are with you my friend. If I can help in any way you know how to contact me.
