When will my life begin?

Do you ever feel empty and alone, without a clue of which direction your life should take? Like someone wandering in the desert, not sure if the path they're on will bring them to their final destination (or a destination at all for that matter). They could just continue to wander for the rest of their lives and never know what their purpose or goal was. 

Lately I've been questioning myself a lot, what am I doing with my life? What are my goals? Where do I want to end up? Is this how I pictured my life? I feel like I'm just wandering and wandering without a goal to travel towards.

As I look at the people around me, they all seem to know which direction they want to take and have a clear idea of what they're final goal is or at least they have a passion in a specific area. While they're all working towards that goal or passion, I'm sitting here wondering what I'm doing with my life. It's at times like these, I feel like everyone is moving forward and I'm gonna be stuck in the same position forever. 

I've asked myself many times, what do you love to do and what can you see yourself doing for the rest of your life? All I can answer is "I don't know." It's true that I do have many interests, I enjoy arts & crafts, baking, dancing, singing, and painting just to name a few but if you ask me which is something I really love and passionate about? I wouldn't have a single clue. I sometimes think of myself as an octopus; I have many different types of interests but none I'm really good at. I have taken different types of courses in the past but I didn't love them so much that I would want to do it for the rest of my life.

Maybe I'm being too picky, maybe I found my passion and I just haven't noticed yet or maybe I just have to look harder, whichever it is I hope I can find it soon. People have said to me "Oh you're still young you have plenty of time to figure things out" but I feel like whatever my passion may end up being it's too late for me and I'm to old to start in that career path now. 

I'm normally a person who likes to live each day as it comes, but it still eats at me to not have a general direction of where my life is headed. It's a dark and scary place to be and at times make me feel very small, empty and useless.

People often say that when God closes a door He opens a window or that there will be light at the end of the tunnel. I feel like many doors have been closed for me already, when will I see the window or will it just be another door? Will there be light at the end of the tunnel or will it just be a brick wall? I'm really hoping the former will present itself soon.
