Hi Hannah, welcome to the forum 🙂 The numbers you state are not high enough to give a definite diagnosis of diabetes, although they are above 'normal'. I think you need two fasting readings of 7.0 mmol/l or more, and in the presence of typical symptoms (peeing a lot, thirsty, tired etc.) - do you have any symptoms? Do you have any family history of diabetes? There is another test that is often done called the OGTT (Oral Glucose Tolerance Test) - they take your fasting level, then give you a measured amount of glucose in a drink, then test you again at intervals. If you exceed a certain level (11.0 mmol/l, I believe) after two hours, then this would indicate diabetes.
Try not to worry! Although diabetes is a serious condition it can be managed very well with the right knowledge, application and support, so doesn't need to impact you and the things you enjoy doing 🙂 Many people discover that the adaptations they make result in them feeling much happier and healthier than they have for some time (true! 🙂) and a healthy diet for peoplle with diabetes is a healthy diet for everyone, so you may be surprised at what you will still be able to enjoy 🙂
Let us know how things go, and if you have any questions 🙂
