LPN school?

Is anyone in here an LPN and if so, how hard was the schooling? I’m considering doing my CNA and going for for LPN immediately after. I’ve heard CNA is pretty easy to get thru so I’m confident I’ll pass but all ive been told about LPN is “it’s hard but you can do it” and that completely discourages me. I just don’t want to waste my time or get further in debt with something I can’t do. Plus I will have three young children at the time I’d be going. I’d love some opinions
