Confused. Growing up?

I'm feeling so confused about life right now.

From 18-20 I was having so much fun and felt on top of the world and on top of the game

From 20-23
Horrible. Too many health issues which cause low self-esteem, low self-worth. However a new me emerged. More determined, focused and driven.

From 23-25
Much healthier. Very driven. Good job. Felt like I had direction

From 25 to now ...I'm 26
Got laid off and have been laid off for six months. At first it was okay. I focused on school, working-out etc. Now, however since I have so much time on my hands, I have done so much thinking and sort of feel confused about people, their intentions and who I can trust versus who I can not. Since I am not consistantly around people as much if nothing at all I feel as though I am becoming an introverted anti-social person. Negative thoughts are creeping back in my mind and it's much harder to get rid of them then before. My job loss has taken a big toll on my self-esteem. I really enjoyed working there. It felt empowering and I finally felt like I was working with a sense of purpose. It does not help that my boyfriend is lost too although a big sweat heart. plus his values are questionable. I don't feel they're the same as mine but he assures me that they are. This just further confuses me.

Is this just a transition into figuring out who I am in life ?
or some-sort of developmental faze?
