Opinion:
You don't sound whiny, it's a lot of changes.
But when you think about it the only thing that really needs to be dealt with is your new job.
The rest are just things happening. They are out of your control and don't particularly need your attention. What is happening is happening, just let it flow.
In other words... There's nothing you can do about it so what the hell? Just take a deep breath and keep going.
