Does anyone else feel this way sometimes?
I just bought a car. My monthly budget has become really tight, but I have credit cards in case of an emergency, and the budget will loosen up quite a bit when I pay off three bills over the next few months.
I have a job I like. I've been there for about six months, and there's no sign I'm going to lose this job. My boss keeps using future tense when talking to me and praised me quite a bit last Friday.
However, since I just bought the car last week, I'm still full of anxiety and near-panic that I'm going to lose my job, which means I won't be able to afford my bills, which means my credit will go in the toilet again (after spending four years repairing it), etc, etc.
It's baseless anxiety. I have NO reason to believe I'm going to lose my job. None. On the other hand, my brain keeps saying, "Nothing is guaranteed! You can't count on that!" and other stupid thoughts.
I know I'm being stupid. I know it's ridiculous. But I can't stop.
My boss told me I can work extra hours, so I'm going to work as much overtime as possible. I've also cut as many expenses as possible, no matter how small. Netflix is only $8/month, but I hardly ever watch it anymore, so there it went. 
I should definitely see a therapist, as I've gone through a divorce, getting a new job, moving into a new place, losing my pets (ex-H has them... mutual decision), and now this (big) new expense. That's a LOT of life changes in just several weeks. On the other hand, I can't afford a therapist, even the ones who do sliding scales. :P
Will this feeling pass? I'm hoping it will, once I get a couple car payments under my belt and pay off those other bills. I just hate thinking I'm going to feel this way for the next few months. Ugh.
I think a big part of it is adjusting to having one income again. When I was with H, I had that security blanket (his huge savings account, his huge income, and having someone to come home to and distract me and make me feel safe and secure). Now that I'm alone again, with no pets, it's just this quiet house and me alone with my thoughts.
