Please forgive me if this seems snarky or insensitive to your situation as that is not my intention. Being happy has no price tag, if you were truly happy with whatever you were doing at Target I am truly sorry you lost your job. However, I suspect that is not the case. If it isn't:
Getting canned from Target may be the best thing that's ever happened to you, a lot of people need a kick in the a$$ to do better. Frankly working at Target is a very sucky job to have unless you're upper management. You get paid pi$$ all, crappy benefits, and you get worked like a slave for it.
Although the economy is poor at the moment there are good jobs out there go get one. I'm not saying it's easy, there's a lot of competition out there now. You'll have to pound the pavement, meet a ton of people, and more than likely get rejected a whole bucnh of times. Finding a good job is more work than actually working. Getting a good job is the payoff.
This may seem mean but it's how it is. I can only speak from my point of view and if I was working some menial job at Target I would not be content with it. I worked the crappy job thing in my early twenties and even rose as far as I could go at the fast food restaurant I used to work at, being by far the highest paid employee there, and I wasn't happy, I couldn't afford to live on my own comfortably, or buy a car that wasn't a POS. Six years ago I decided to 'make something' of myself and I don't regret it at all.
