OTOH, they could use one for *him* - physically (being the hero, he gets dumped on rather more than the rest) or metaphorically as he is IMO clearly reaching the limits of his strength, and while Cally may be able to stand in for the former, none of the crew he has *can* fill the latter role.
I have a feeling Blake is a very difficult patient - remember his reaction in Horizon when Cally tells him he's ill, or the way he behaves at the end of Star One. After all, a doctor is also a kind of authority, and I can't imagine Blake *obeying*, not even when it's for his own good. It must be awfully difficult to convince him he ought to stay in bed, take his medicines, do what the doctor says...
As for psychological problems, he acts in accordance with the overall stoical atmosphere of B7 and tends to work them out by himself. Significantly, when he almost gets killed in Trial because of this, he says, 'Next time I want to think, I'll do it in my cabin.' Note that he doesn't say, 'next time I'll confide in my friends'.
Also, as you've once noticed, he must have gone through an extremely difficult period in those early episodes, when his memories started coming back to him, and he was trying to put the pieces of his former life together and deal with the painful emotions this caused. And yet there's no evidence in the series of him trying to share this burden with Jenna or anyone else. Actually I have a feeling that most of them (if not all of them) didn't even know about his brainwashing treatment - it seems the first time he mentions it is SLD. Even then it's just a short phrase, 'Oh, they did a memory erase on me.' It's not easy for him to talk about that, but OTOH, there's no trace of self-pity in his voice and he doesn't ask for sympathy.
