Hi and so sorry to hear of your burnout, it can happen to many of us at some time and it can be such a big struggle so here is a link that may help. Take care and remember you aren't alone.
It is literally one day at a time, just try and stay on track with testing and talk to your GP/Consultant. Also talk to others on here with type 1, we've all been worn down with this at some point or other, coping with what life throws at you as well as managing a needy condition is hard work, but talking to others does help.
