Really shaken and unsure how to move past

So im a very new driver got my CDL in November and today I had my first accident no one was hurt thankfully for a bit of context my Aide was reading the route off to me since I was covering and had said we do a U-turn at a point on a country road and I was skeptical but went a head and did it but ended up sinking my back tires in a ditch and burying my back bumper and a portion of the bus in the dirty and being at a turn angel the bus was tilted (yes it was my fault completely I should have known better and not done it at all) I ended up calling in on my PM route bc I can't stop thinking about it and how it could been so much worse and if we where only a little bit more into the turn the buss could have rolled so my question is how do I get past this and keep driving
