YOU are not your disease! YOU are worth loving! YOUR life isn't of less value because you're sick, in pain and need more help/assistance! Love is in sickness and health! YOU are not a burden. You are a gift. Life is a gift. Loving anyone is a gift. Being loved is a gift.
Please know this. Please believe this. Please live with this reality. Life is too short to throw away happiness because you don't value yourself enough.
