Hi, I'm reading too, but I'm away and the internet is a bit hit and miss, I haven't been able to find any 'out' today, just booked into an Inn for the night, fortunately they had a room so I didn't have to use the stable... Oh, no baby either! thank fuck 
I haven't been on any of the drugs you have, part if me is very relieved and part of me feels I'm missing out on something... So, I have no idea what is what or what any of them are doing to you?!
I'm sorry you considered/planned/intended to OD last night and very pleased you didn't.
I don't talk about it much on here as it's something I feel quite private about, but I have diabetes too. My HbA1c is controlled if I low carb, but I have fallen off the wagon most spectacularly & I'm not exercising at all enough. I am really put to shame by how well you are doing with food & going to the gym, all while coping with the rest if this shit as well! I can't even scare myself into it right now... WTAF is wrong with me?!
Re the HTT & what you need... They seem to be scaring you & stressing you out, which is awful :(. But it's clear to us reading your posts that you do need help and certainly appear to need something to balance you out. Is there any way to get the help you need from someone you trust?
You say you are fine, but you really aren't. You are up & down more than hookers knickers Santa's sleigh on Christmas Eve...
Is there anything anyone can do that would help you?
