You have the right attitude. I have had 2 bouts with cancer with almost 2 years of chemo and am still here. Mine was ovarian cancer stage 3.
Keep your Faith in the LORD he will not give you more than you can handle.
I can't tell you how many times I have seen ladies or men who are going thru chemo treatments and been able to witness to them. It's not an easy road to go down but remember, Our Father in Heaven is holding you in His hands, He is in control and you will get thru this.
Prayers for you and your family may the Lord just give you a spirit of peace that is beyond all understanding and a speedy healing.
If you ever need to chat, a shoulder to cry on, or just vent give me a shout.
