Problems with my job - what happened

Remember me saying I wanted to quit my formal job?
Well, I did. Kinda.

In December I had a quick conversation with the assistant of the big boss (aka supervisor), in which I told him about how I was unhappy to work for them and how I wanted to leave the job.
As we have a 1 year contract, the guy just told me "You must give me your Resignation Letter and only after 1 month you can stop."

I didn't give any letter as I was waiting to get paid.
Well, in the beginning of the year he came with this completely different conversation saying "You know you're not working with us any more from next week...", and that he "accepted" my verbal notice.
More, he told me on Friday 2 January when the last day of our rota was Sunday 4 January.
I still fought back demanding at least 1 week notice as it says in the contract. He agreed and said he would talk to the boss. No answer.

Worries about the future

I think there is nothing worst for the soul than suffering in advance for something that might not even happen. It's like an endless escape from a terrible nightmare.
Well... that's one of my problems.

I remember when I was younger and I couldn't be happy due to all the pressure I used to put on myself. It can be really tough, but one of the biggest steps towards reaching happiness is to learn to accept and learn with the past, enjoy and think in the present, and calmly deal with the future as it comes.
However this is a big lesson that you get to learn during all your life and sometimes it seems impossible to think rationally.
