To dream of having diabetes represents a problem in your life that forces you to give up everything that feels good because not doing so may embarrass you. You may have difficulty enjoying the sweeter things in life. Pleasure or enjoyment may feel like it’s dangerous for some reason. You may be experiencing very strict rules or spiritual principles.
Diabetes in a dream may also be a sign that you are doing everything you to stay stable by avoiding things you like. It could also mean you are going way to far to prove yourself.
