What you are experiencing with the change in therapists is a common pitfall for many people. I don't know how the therapist handles it in private, but they aren't supposed to get emotionally attached or show much empathy. Actually, that is one of the things I don't like about them. It doesn't surprise me that there wouldn't be a specific goodbye time, even if he knew that it was an issue with you. Breaks with therapists are supposed to be clean and final. When they feel you no longer need therapy, and the sessions end, they will not respond to calls, letters or e-mails of a personal nature. If you were to become a patient again, then the relationship would resume, but otherwise, they just break.

Therapists are all different, and if the therapist you have thinks that you don't need more than one hour a week, she may not be what you need. You know how you feel and whether or not the current therapy is working, which I assume its not. If you went to a physician and they told you that you didn't need pain medication for a broken leg, you could just as quickly find one who would say you did. You need to find a therapist that is willing to work with you on a level that you feel comfortable with. If you are really having a lot of trouble, one hour a week is not very much time. Ask for a referal or see if you can find one yourself.

I don't know what kind of geckos you have, though saying that they are common makes me think they are leopard geckos. They have a lot of problems. Your care may not have anything to do with why your gecko died. I see several over the course of a year, and some of the sickest come from very good homes with good care. They tend to have shedding issues which lead to serious eye infections, mouth infections and anorexia. Even though they don't have eye caps per say, their skin covers a small area under the eye lid, and unless the humidity is just right, they tend to not shed that skin. The same goes for the mouth. The old skin sets up an infection and once they can't see well, they stop eating. If you have a veterinarian who is familiar with reptiles, take a couple of your other ones in and have them checked out.
Ideally, they should have 50% humidity which is hard to maintain.

If your ex is coming as a guest, and you feel that you may not handle it well, ask her if she can wait til a better time. You sound as if you are having a bit of a crisis, and that may not be the best time to entertain someone who may come down on your emotional issues. Since you are on good terms, she should understand a rescheduling of a visit.

Take a deep breath and see if you can deal with these problems one at a time. Make yourself a list and prioritize.

Hang in there.
