I can't breathe through my nose?

I have always been a mouth breather. I find it absolutely impossible to breathe through my nose, I feel like I am suffocating and not receiving enough oxygen. I snore extremely loud and my boyfriend has to sleep in a separate room as it is unbearable. Is there anything I can do about this? I haven't yet visited a doctor or GP so suggestions for this would be very helpful?

When I was younger I did unfortunately fall face first into a tree stump and it was my nose that received the most injury and I'm not sure whether this could be a contributing factor?
