PTSD, aftershock, and financial issues

It’s another day of doing nothing for me – almost- but for a first time in a week, there is no hidden mounts of pressure, no insurmountable challenges and feeling of despair. I’ve just receive my next chunk of money, my next payment, and the suffocating feeling like there is a ring around my heart(or lungs) constantly squeezing, has released a little. I can finally breathe. For about 10 days, I’ve reverted back to whom I was when I was scared, panicked, in shock and generally depressed. Sure, partly for money reasons, but let’s face it, it’s not only that. Once again, I’ve went from a period of regular weekly income, to having almost nothing. Literally- nothing in my bank account or wallet. Spending my last money for the bus and wondering how I will pay the next bill. Again. It’s not such a novel concept. I freelance, which means I’m floating from periods of getting more than I need, to periods where I just have to be patient for a month or two while I am trying to get new work.
But this, it’s like a physical reaction, and I completely lose all my logic, and ability to get myself out of that situation. It’s debilitating. I’m just starting to think there’s no getting out of it, and it’s all dire and impossible, until, when I receive my money, there is a day of shock and relief, whilst I’m fighting to forget that paralyzing fear…And then I’m back to real life. Like I just awoke out of the haze(which I pretty much did) and became real. It’s like my reaction to losing weight. It’s one of the hardest because I wonder if I can ever get over it.
