Slightly paranoid

Im going to try to explain this the best way I can. I graduated in May and passed Nclex on the first try. I've been hunting for jobs ever since at my hospital where I already work as a tech. Finally one application shows under review.

I happened to be helping out a trainer on a training day and we got to talking, she took me to visit 2 units one of which I had my application under review (let's call this unit x) I thought awesome this could give me a leg up. Another unit (we will call this unit y) that I had not applied to agreed to schedule a share day with me. Well before my share day unit x called me for an interview and they offered me the job on the spot, but didn't want an answer unit I did my share day on unit y the following week.

The following week came and I did my share day but no one was around for me to talk about employment. I had to give unit x an answer by the end of the day and without talking to unit y I only had one choice, to accept unit x's offer. I call to accept and I'm told "ok GREAT! You will hear from me as soon as I talk to the people running the new grad program".

A few days later unit y called for an interview and I said thank you but I accepted an offer on unit x. I was asked to still come in to see what they had to offer. I said ok sure, can't hurt to just go and listen.

I finish the interview and I'm told I did great and I will hear from them soon. I hear nothing! Ok whatever I think it's kind of shady they were stepping on the other units toes that way anyway. I go online to my application status and it now says closed with no word from anyone. It doesn't say I was denied like it normally does, it simply says closed.

My issue with this is that I'm not hearing back from unit x anymore either and I'm worried that by allowing them to coax me into this interview I wasn't comfortable with in the first place just screwed me out of either job.

Opinions?
