Suffering ED from an injury

My penis suffered from a motorcycle injury about 2 weeks ago. Following the injury, it swelled up for a few days. During these few days, it hurt whenever I moved it. I noticed that during its flaccid state, it grew larger probably due to the swelling, but after a week it returned to normal and it does not hurt anymore. BUT the problem is that I cannot get an erection with or without stimulation. I researched a bit online and came to think that I might have a case of high flow priapism and that the nerves in my penis were damaged during the injury. From what I read online, these nerves take a long time to heal (like a few months), so I am trying not to panic and jump to conclusions. Should I be worried? Is there anything I could do (or not do) to help speed up the healing process? I am trying not to  stress about it too much because I also read that stress and anxiety does not help at all. Thanks in advance.
