I would say go ahead and email your T. If you know the boundaries and your T allows it then take full advantage. That's been the only way I've been able to talk to T about some stuff but similar to you I've been feeling kind of low and lost as well and I dont want to tell my T that because I have a tendency to solve things on my own (or try to). Go ahead and email whatever you want to know and i'm sure even a small response will help you out! Goodluck!
