The intent is apparent from the first line of the spell description (NO!)
The first line does state (emphasis mine):
You sacrifice some of your health to mend another creature’s injuries.
This heavily implies that you are not eligible, but the mechanical description sentences that follow (see below) do not list a requirement such as that when actually choosing the recipient of the hit points.
Jeremy Crawford does reinforce the importance of that first line and that You should not heal yourself with Life Transference (emphasis mine.)
The first sentence of life transference expresses how the spell works: "You sacrifice some of your health to mend another creature's injuries." That's someone else getting healed, not you.
Physician, heal thyself?
The spell language seems to contradict itself. The second sentence describing the mechanics of the spell (Xanathar's, pp160) requires the following (emphasis mine):
You take 4d8 necrotic damage, and one creature of your choice that you can see within range regains a number of hit points equal to twice the necrotic damage you take.
The mechanical requirements per that sentence are that you take damage, and that you then choose one creature within 30' that you can see to regain hitpoints.
It does not state that it must be one other creature or that you can't choose yourself, so there really is no limitation here that precludes you taking the damage and receiving the hitpoints.
This is highly unlikely. Crawford has clarified that is not how the spell works, and this is most likely a problem with the wording of the spell in that second sentence.
We can take from the name Life Transference and the language of the first sentence to conclude that you are not supposed to be able to do this to yourself.
