Working For Nothing

This feeling has been recurrent, but it's really frustrating me today and I just need to get it out somewhere so that I won't continue to rant abut it to my wife or loved ones and upset them with my constant stream of negativity.

I work a full-time (40 hour) medical position at $15 or so an hour. I work 2:30pm to 11pm. Lately I've been putting in applications at both other companies and internally at my current company trying to get a day shift position. I find working in the evenings has begun to contribute to my depression (which isn;t uncommon among people who work off-shifts. Google search "shift depression" for more info.)

However, I've been striking out or just not hearing back for weeks at a time.

Despite making what I do, it isn't enough. I'm missing work for my depression or due to physical illness still. Even when I'm not sick, it seems like all I'm doing is playing catch-up with bills for the times that I am. I never make enough money. Everyone's answer to this is to go back to school so I can climb the ladder in my company. I have to have AT LEAST a bachelor's degree and currently have no degree or college experience at all other than a trade school certification.

I can't afford to go back to school, nor am I working a position that allows me time.

I'm not sure if I want to stay in medical. If I went back, I would go for IT.

Again. I can't afford to go back and I'm working bad hours for school.

I want to travel to go see friends abroad and have expereriences worth talking about.

I can't afford it.

Literally no matter what it is, I can't afford it.
