"the highest, soaring, creative sativa for daytime use."
My first sativa will always be Kali Mist, although it doesn't fit your request:

.
Other options - this is a list of strains I've put together to treat depression, some should fit your needs.
Bubblegum -
Serious Seeds: crystal clear euphoric high. Very potent but functional and clear. Tastes like pink bubblegum and icing sugar. A treat, I know it works because I go through it quick.
(stimulating)
Kali Mist -
Serious Seeds: an up-opiate; nothing is wrong; bliss; cuts through moods and other highs/stones; spice; my favorite strain (my pheno takes 18 weeks, some take 10 but will have different effects)
(neither sedative nor stimulating, but you must overcome Bliss to move)
** Kali Mist is like being in the Nexus.
From Star Trek the next generation movie where Kirk comes back to fight Sorun. Everything is so perfect you never want to leave, and if you're bending under the weight of clinical depression you'll do anything to get back.
The closest effect I can compare it to is the opiate stone from Percocet, except it's an up-opiate and there's no withdrawal. To cap it off you don't chase the dragon, you ride it. 2 years and the high just keeps getting better and better as I learn to grow and cure better.
I Can't recommend Kali Mist high enough but considering the long flowering period you may be better off starting with two shorter flowering strains and add Kali Mist as a third or later strain, once you have bud on hand. Tell your girlfriend that this strain is good for menstrual cramps. It won a Cannabis Cup with all women judges.
Kali Mist - Serious Seeds
AK47 -
Serious Seeds: soaring high, rocket fuel, non functional. Smells like dead skunk during flower, needs odor control. Will lift spirits almost immediately but the power of the soaring high may cause anxiety if you're not use to it.
(stimulating)
Jilly Bean -
MzJill (Subcool & TGA): High type-Happy, mood enhancing, humorous, energetic; Smells like orange skunk or tang/ Taste so much like Dreamcicles you will not believe it.; Extremely up beat and happy buzz great for depression and bad days. I got a pheno called "The Candy Store" - huge producer, potent and reeks of blue jelly beans. Like dripping syrup.
(stimulating)
Pandora's Box -
Subcool (TGA): the Cheshire Cat strain; High type- Zooming, Happy, Grinning, anti depressant BIGTIME!;smells: It taste like NL5 to me but its very industrial with a slight citrus taste and a undertone of spice and hash One female has been named Cherry Lethal lemonade. I find this to be the most potent of Jillybean, JTR and PB - dissociative.
(stimulating)
Strawberry Cough - (Dutch Passion or preferably a clone from a dispensary): the best anxiety melting strain I've grown. The pheno I had was weak and tasted bad, but melted anxiety like steaming water on butter. I'm growing 4 more from seed to look for a good mother. People review it as a very potent high when you get a good pheno.
(stimulating)
Flo -
DJ Short: tastes like musky grapes; unique motivating high; my pheno is a very small producer but finishes right on 8 weeks - chopped yesterday at 55 days this run. If you need to get things done while being happy this is the strain. Small producer
(uniquely motivating, a must have if you have trouble with motivation during depression)
You can get all of these strains from Attitude, they deliver world wide.
