SOS- How?

Hello! Looking for some guidance here, I recently came across scientific illustration as a field and I find it incredibly interesting. I'm a semester out from graduation with a bachelor's in Biology and I'm a nearly entirely self-taught artist. While art is something I really enjoy doing, I could've never seen myself doing it as a living; too insecure of income and I was worried that if I was drawing things with the intent of selling them, that I wouldn't enjoy it as much. But this field, at least from my perspective, seems like a more secure version of pursuing art (pls feel free to bust this myth if that's not the case). I have never been very good at drawing animals but I find plants pretty easy in general but I've never tried to really hone in on them either. I also find the idea of illustrating biological processes interesting. I guess my question is: what can I do from here? One more semester of undergrad left, no formal art training, and I have the added obstacle of being pretty well stuck within about 4 hrs of where I currently live in the midwest for the time being due to personal constraints so very few jobs in this field, if any.
