Am I friendzoned?

Ask her.

Have you been on a date with her?

In general:

If you have to ask if you were "friendzoned", yes, you were.

If your set of ideas about the opposite sex includes the concept of being "friendzoned", you usually will be.

Yes, we went to the cinema a few times and she'd lay down on my arm

I'm planning to tell her what I feel about her next time we meet.

For pete's sake, just ask her out. How the name of sense should we know if you are friendzoned? (edit: Ok, I see you have been to the cinema a few times according to your last post. So why not talk to her and tell her how you feel.)

Personally, I think a big piece of the puzzle is missing. You start by writing that you two have been talking a lot lately, then finish by saying you had stopped talking for a long time until a few days ago. Those two statements seem to be a bit contradicting.

Females tend to be fickle. Take what you can get when it is offered.

Well, that was my bad. I forgot to edit it out.
Let me be a bit more specific then:
We used to talk a lot before she stopped talking to me, she got depressed (I didn't know) and stopped talking to me and many of her friends, a few days (4~5) she texted me telling me she was sorry and how she missed me. I forgave her and we started talking as much as we did before, she even invited me to her bday party with her family and 1 girl friend only, plus we're going to the cinema the week after. Friendzoned or not I'll still tell her what I feel, but I'd like to have other people's feedback here so, depending on the replies I could get an higher confidence when talking to her when we meet.
