Many bioinformaticians come from either biology or CS so this is a common question. In general if you are from CS you have to learn the biology, and if you are from biology you will have to learn to program. Both types will also usually have to learn some statistics as this is important for research. You mention that you enjoy the field which is perhaps the most important thing. I recommend finding a good masters degree in bioinformatics which should introduce you to many of the basic topics. A bioinformatics masters degree will also make you more competitive than with a degree alone. You'll need a PhD if you want to stay and go further in Academia.
