Dear BullGem,
Welcome to Beyond Blue and well done for reaching out.
I feel the need to start by asking what a DVT episode is? I haven't heard that term before?
Anyway, in relation to your problem, I would hazard a guess at saying that every one of us at one time or another has had both a difficult colleague, and a mouth that runs off before our brain engages. I know that I have, plenty of times!
Perhaps the thing to focus on now is what you can do to make a difference in the way you can interact with your remaining colleagues? You could perhaps try and explain yourself, but I would also suggest that if they don't want to talk about it, or don't feel the same way, then perhaps take it as a hint to just get on with the job at hand and give it the best you have. Try to focus more on what you like and what you do well, and build on that.
I too have a colleague that is very different from me; we are chalk and cheese. But there are days when we can get along and it's okay. On the not so good days, I tend to feel some anxiety, but I have learnt to write out my frustrations in a journal and then I am able to let it go and move on. I gotta "get it out" but I also need to make sure I'm not harming anyone in the process ..... In other words I keep my inner bitch to my inner circle .... As best I can anyway.
I don't know if any of that helps, but at least now you know you've been heard. Take care. Hope things improve soon. Xo
