I probably could have driven myself through a lot of my treatment, the last 2 weeks, no. Luckily my husband and I are both retired so he drove me most days then would take me to Jamba Juice for a smoothie.He even got a round of applause from the staff when I rang the bell at the end of my treatment. It meant a lot to me and hopefully your husband can appreciate what you are doing for him. Use every bit of help you can get, things are going to get worse for him, and you, from now on. If you haven't yet, get some emesis bags from Amazon and keep them on hand for the vomiting, life saver! You will get through this! I encourage you to cultivate relationships with people who you can confide in about your struggle through this. Even at the facility your husband is being treated at, they surely have counselors or psychologists that can help the caregivers too, maybe look into that.
