How do I stop living in my car? I'm fucking broke broke, dude.

So it's going nowhere with this girl at work. Another week, I try to get near her, she doesn't acknowledge me. And what's worse is that I started daydreaming about her at work and it's getting hard to focus. At the same time, I'm afraid she will reject me if I get bolder. So I decided to put an end to it: I'll just write a note, give it to her and hopefully I'll be able to get over it

"Hey, I'm X from the X floor and I like you very much. Here's my number if you want to talk.... "

So i've got couple options
1. I'll leave the note on her desk before she arrives. Risky as it's actually frontdesk, lotta cameras and someone else might see it
2. I'll have some flowers delivered to her and the note hidden in the bouquet. Risky as there might be people around when she gets them
3. Have a work mate give her the note. Risky as I don't trust these guys
4. Hand over the note myself inconspicuously. Risky as it requires some dexterity I'm not sure I have it
5. Socials. I'll send friend requests to her Facebook and Linkedin and, once she adds me, I'll tell her there. Risky as she might not add me.
6. Thinking of sending her the message on the company internal messaging app. Might be safest way.

Which option should I go with ?
