It can happen to any of us, but you should have contact details for your DSN if you feel you need help with something. My diabetes clinic appointment the other day was cancelled, (Covid-19) but I had already been in touch with my consultant using email, reporting back on my current situation with BS results. Have you got contact details for the people you normally see ? If you haven't, try asking for them. Sometimes, you only get what you want if you actually ask straight out. You should have a phone no. for your DSN at least.
