Just bought my first ever acoustic guitar (a Taylor Big Baby) used on a local craiglist-equivalent for about 130$. It came in the original gigback which had only one back strap left. I decided to bike home and strap the guitar crosswise on my back.. in hindsight I should have realised that the one strap could not be trusted. Anyway I biked for about 3m before the strao broke off completely and the guitar fell on the asphalt. Upon arriving home I found the damage you can see in the picture :( The tuning peg of the G string was very crooked, I pressed it back in shape and for the moment it seems relatively stable..

What do you think I should do? try to glue the piece together myself? get it done professionally? try to get a replacement headstock? thanks for any advice and condolences!
