Did you ever plan? Were you a capable planner? If you had the skill at one time, you still have it. So, I'd close my eyes and ask that part of me to help me with planning a new life, that will be peaceful, fun, and much better. In otherwords, tell yourself you know you have the skills, and you need to find where they are generated from in your mind.....tap into that place. If I'm in a stressful situation, I ask for inner support in a quiet moment. I'm a paper planner....so I type everything out....so I won't forget. You can have your plan in your phone or notes......to add to as you think about it.
Were you medicated or are you off medications? If stress is going to increase, you might want to go see primary care doc and get meds adjusted.....rather than waiting till you can't do anything. You using marijuana or drinking more regularly (that can make planning difficult). Eating properly? If you aren't getting lots of protein (not carbs), and vitamins, this can cause you depression, your brain won't work, and even cause lots of fogginess where things aren't clear and problem solving takes a real dive. I take 2 Flinstones chewables a day, plus some other vitamins. If you can't afford vitamins, you can get your doctor to prescribe you them....if you have insurance. But physically, the body doesn't work or think well without the right nutrition. I personally drink premiere protein shakes once a day, as a supplement, to insure I get enough protein and vitamins. They are high in protien and vitamins, and low in calories. Make sure you alsoeat breakfast....that can make a world of difference in how the day starts....if you aren't. Lastly, if you aren't getting enough iron or protein, both can cause weakness, fatigue, irritability, and brain fog.
Getting exercise? Getting out of the bedroom every day, for the majority of the day. Getting out in the sun for a nice walk will help get your vitamin B levels up.....it's the quickest way....only 20-30 min a day.....might as well walk. Exercise activates endorphines and the chemistry in your brain, to help you think. So, if I was making a plan, I'd include my meds, meals, medical appts, exercise, and sleep.....proper sleep helps you to be able to think........and if you have a phone, there is a wonderful health app on there, which records your sleep, steps per day, blook pressure, and quality of sleep....it tells you how many hrs of sleep you get every night, a weekly average, and gives you feedback on ways to improve quality of sleep. So if you are having sleep issues, try tracking your sleep and try getting into a routine, that has been a God-send for me!
As far as your fear about your husband threatening suicide. You have options:
1. Ask him to come to your therapy and you tell him there....
2. If he's abusive, have a suitcase in the trunk phone, meds, credit cards/cash, all important papers you'd need, and your car keys and other things you'd need to be away from home and a place lined up to go beforehand for the night.....just so you are safe. So, you got a friend to visit while you figure things out....family.....a shelter?
He's responsible for his own reaction. Saying he's going to kill himself is manipulative in the worst way. However, I'd write down the number of your local suicide hotline, and leave it in several places (near his bed), on the fridge in case he balls it up and loses it in a fit of fury.
