I cry all the time in session, too. Generally, T or MC just keeps going, or they might give me a moment to collect myself if I'm really upset. I'm OK with that response. I'd be really upset if they left the room--it would make me feel like something was wrong with me. If I use the last tissue, they might offer to get more tissues.Once, recently, when I got really weepy, MC moved the trash can from under his desk to in front of me, saying, "That way, you won't have to pile up tissues on your lap." It felt very caring (only I'd find someone moving a trash can to be caring!)

Possible TMI warning: I've apologized before for being gross, if I've gotten really snotty, and they've both reassured me that I'm not gross. (I think some of that comes from, like Daisy, my parents having issues with me crying when I was a kid. Or blowing my nose at the table, stuff like that). MC usually shakes our hands when we leave, and on Monday, I'd been crying a lot and using lots of tissues, and I said to him I'd understand if he didn't want to shake my hand because I was all snotty. He was like, "Moderately snotty or extremely snotty?" I said, "Just moderately," and he held out his hand.

I find it odd that your T said he might leave the room--maybe ask him about that if you're concerned. It's possible he only does that if the client asks if he could give them a minute, or maybe he offers first. I doubt he'd just see a client sobbing, get up, and walk out. I'm guessing he probably personalizes his reaction to the individual client.
