Not all that great these last few weeks. Feeling very precarious for no real reason. Early 40s, good and established front end job but feel tired and frazzled all the time. I had to start again financially after pandemic and divorce. Feel very uneasy about the future and income and job prospects, even though I’ve had good feedback and job offers in the last 12 months. Side projects have ground to a halt feeling rife with pointlessness and inadequacy. They’ll just fail and so why bother? Craving certainty and comfort but expecting that from random externals is unwise. I know this but still I worry and dwell and still tell myself that I’ll be found out, that I don’t deserve a well paid job, that I won’t be able to maintain this and I won’t be able to look after my kids or myself. I feel oddly trapped by expectations and obligations of a good wage. And thanks for asking. I feel better for just writing that down.
