Please don't take this the wrong way, I'm not criticizing you. You are worrying about things you cannot control. Focus on putting money aside in case you need it. Schedule all your medical appointments and check-ups now, just in case. It's better to be prepared and take care of things now while you have the income & insurance. None of our jobs are guaranteed & we can be let go at any time for any reason. I'm not criticizing your feelings & fears, but jobs come and go in life. Don't let this fear of layoffs eat you alive. Get your medical & financial situation in order now, so you are prepared.
