Hi Alice,
We all know you've struggled in the past and you are struggling pretty hard now. I don't think people are trying to slam your neighbor, but they are thinking "Is she a doctor?" Their heart and head are in the right place on that. They just want you to be better.
I think you need to follow your doctor's advice. Quitting HRT has other implications as well. How does that plan into your overall transition/life plan? Have you thought about and discussed larger issues like transition and your next year with your doctors and therapist? I think your plan for HRT will depend a lot on where you are going with transition and what your plan is.
I hope you don't take this the wrong way because it comes from a good place, I promise. I really think you would make a lot of progress if you could get the therapist to help you focus on the root cause of what's bothering you and making you down instead of the symptoms and the feelings themselves. You know that a lot of us give you advice but it's because it's hard to watch you talk about feeling the same way and we want to see you in a better place. Are you stressed and if so, why? What is causing the stress? I don't mean the actual feelings you are feeling, but the "why" behind them. Where are all of these feelings and emotions and instability coming from? I think if you can start to touch that, you'll be on the path to recovery pretty quickly.
Here's the thing about hospitals, particularly in-patient psych hospitals. They are designed for a purpose. They take a person experiencing major, major life trauma and remove them from their daily life basically, place them in an atmosphere that is insulating and therapeutic. You have no worries in there, people take care of your needs, you have food, clothing and shelter. There's no job stress. It's basically a break from reality to focus on what's making you ill. I was in that environment for three months when I was younger, trust me, I know how that feels. I think you really need to recognize that. It's a place where you might feel drawn to, especially right after being there. Think of it more as a place where you can gather your strength and get pointed in the right direction.
You've been so weak emotionally lately that you need to get yourself back to where you can function. You remember those days, it wasn't so long ago that you were there. I know the gender thing has been rough for you, but you can work through it. You are strong. Cyclists have a tenacity that is rare. If there was a way for you to take that tenacity and use it to recover, can you imagine? Wow, you'd be on the path to healing pretty quickly

You are the same person you've always been Alice. Whether the clothing changes or the appearance changes, you are still you. You know we all support you and I hope you know that. We want to see you start to make progress, just like you do

Stay strong, you can get through this, Meghan
