When we're apart from someone, they aren't there. All we have during separations (after death, termination, moving away, etc.) are our memories and thoughts of the other, conversations or activities we shared together.

My T did a lot of travelling, would often be gone to the other side of the world for 6-8 weeks a couple times each year. When we terminated, I gave her a small, expensive, sand "globe" art piece, predominately her favorite color (blue) to remind myself that she would look at it and think of me and I could think of her doing that and feel connected.

Think about your favorite times, conversations, tips or tools, jokes, etc. that T has shared with you. Remember specifically why you see that particular T, that particular person. I can still hear my T in my head telling me, "Oh, you're stubborn!" 40 years after she said it and it makes me smile. Remember and use some of the things your T has said to you, do a thoughtful, "Well, T said X so I'll try X" when you're confronted by something. Remember the A and the email, merge the two together so you work to get more As and feel good when you do because you know T enjoys your success too. Getting T into your day-to-day life will keep her more "real" all the time. Ask her her favorite fruit. When you go to the grocery store, forever more you'll associate that fruit with T and enjoy it.
