Hi there!
First off, welcome to PC

I'm glad you feel at home with us already

Sounds like a nice therapist. Have you asked him for a plan?
Honestly I wish I could tell you that there was an easy way to get out of depression but alas it tends to be a lot slower and gradual than that. For a long time I was going to my therapist and I really wasn't seeing any changes at all (now that might be partially because my therapist isn't amazing haha but she isn't bad either) until I came to the conclusion that therapists are there to facilitate learning but they can not learn the material for you (kind of like a tutor for your mind). Now, if your T isn't doing that for you, then you definitely should talk to him about it or find a new one. Especially when I was in a major depressive episode, my T was giving me sheets for changing my thinking, affirmations, and other homework to do but at the same time, what I was feeling was extreme self-worthlessness and etc so I'm not exactly sure what he should be providing to you for numbness and etc.
Exercise never hurts since it releases endorphins but I know this book helped me a fair amount: Feeling Better by David D. Burns. It's more of an informational and while it's super long there are a lot of stories and exercises in the book to help. There are plenty other books that come well recommended from Amazon though so I'd take a sift through those as well
If you are really interested in a faster solution though, I would suggest talking to your prescriber and talking about the numbness you feel and if there was a way to up your dosage or add something.
In the meanwhile I'd definitely recommend trying to pursue new hobbies. Also, while you don't want your friends to know, I have definitely found it very therapeutic to tell some of my friends. My roommate in particular will come knock on my door if she hasn't seen be all day which is really nice.
Best of luck!

Keep us posted!
