I feel like my life isn't moving on?

Its like im stuck in this haze. I feel like im not going anywhere. Anthing I do, I have the same feeling. If i go to a rollercoaster theme park, I feel a little happy, but deep down, i dont feel anything. Its the same feeling for everything I do. Alot of changes took place in my life, like moving into a new & better house, reconnecting with old friends, but its like nothing happened. Like I said, its like my life isnt moving forward. Its really hard to explain. But why do I feel like this?
