Newly diagnosed and needle/hospital phobic

Hi. I've got squamous cell carcinoma of the anus, which as I have Crohns didn't come as  major surprise. I have appointment with oncology on Friday to discuss my treatment plan. I know it will be radiotherapy and chemo - just not in which order. I have a bit of a problem with needles/blood/hospitals in general which is going to make things rather difficult when it comes to chemo. Any words of wisdom or hints/tips for me. Thank you
