I NEED HELP

So here goes... I've been married since I was 17(husband is military). I'm not going to give you the whole background and details because it's a lot.

I'm now 20,21 in September. I find myself more unhappy and irritated than happy. I want to be on my own and live my own life. I would like to divorce. Once again, not going into details.

What I need help with is; I don't know normal life outside of this life. And I'm scared.

I don't want to move back with my family, I don't want to live in the mid-west, I want to move to California, I'm currently up in the Pacific Northwest.

I don't know how to find a place to live, like an apartment.

I don't know how to get my car in just my name.

I don't know how to go about health insurance.(the military provides it now)

I don't even know how to get WiFi...

Im afraid to pack up my stuff, I have three cats, I'm afraid to move everything and my cats...

I don't even know how to file for a divorce or what the process even is....

Even the little things that I don't know how to do like change a flat tire to hooking up my play station...

How do I set up automatic payments for my car?

I'm not even going to have a job right away...

How do I get taken off the credit card and the regular bank account? What do I do about the money in savings?

I literally feel like a fucking disaster...

I want to cry because I feel like I'm stuck...
