It's really not that bad. Do you have a valid Ausweis? Does it have online functionality? If not activated, do you still have the letter with the PINs?
If so, you only have to create a BundID account. Your university probably sent you an email with an access code yesterday. Apart from the shitty waiting room, it's really just: Enter the codes your uni sent you, login to your BundID, let the form be autofilled and click 'beantragen'
Edit: Apart from the Amt(TM) experience, waiting in a virtual room for your turn (which gave me troubles in the beginning and I had to wait several 30+ mins turns due to...technical reasons or whatever), I was surprised how easy it actually was and all the crying I've read so far is rather exaggerated
