Hey there,
I'm sorry you are feeling this way.
I totally get what you mean though. I feel like this a lot although I haven't been diagnosed as well. I'm pretty sure I have what you do and the best advice I can give you is to just keep rolling with it and eventually you will get through it but if it gets too rough, you might want to try and get some help. I would if I could.
I hope you're feeling better.
(Sorry this post wasnt that much help!)
