Experiencing a lack of energy can become a problem for all kinds of reasons, without those reasons being obvious. I find it pays to start with the physical considerations and work from there when trying to deal with this. It isn’t always possible to figure out the cause and deal with it directly, but these sorts of things are always worth checking and tend to help.
Getting more rest and more sleep can help a lot, even if the problem isn’t a lack of them. Emotional and mental processing can take time and energy, so gentle down-time can help fix a number of things that may be exhausting you.
Good food, being properly hydrated and being at the right temperature for you, are all really helpful things. If I’m low, I’m more likely to feel cold and will benefit from warming up. Washing may be restorative.
Sometimes it helps to stimulate yourself with some moderate activity. I suffer poor circulation and I definitely benefit, some days, from being more active rather than less. It’s a case of determining whether it will benefit you. Moving the blood around can encourage healing. Sometimes a bit of adrenaline is the right answer.
If my brain is tired then I try to do things that are mentally restful – here physical activity can be a great help, especially anything you can do at a gentle pace. I find crafting helpful, but reading isn’t reliably good when I’m brain-tired. Also be wary of mind numbing responses – shite TV, alcohol and the like can feel like a relief at the time but they aren’t giving you anything restorative. Escapism is fine, but make sure it feeds you.
I can feel low when I’m under-stimulated mentally. In which case, a creative challenge, exposure to creative work, or something I can get my teeth into is the answer. Boredom can also suck away energy, and generate apathy, so needs watching for – if you’re dealing with yourself as though you are exhausted when really you’re just devoid of enthusiasm, you can end up doing all the wrong things and making yourself feel worse.
Low emotional states can be protective. They can be a response to overload and be a way of stepping back from more than you can bear. The answer to a loss of emotional energy is seldom to be found in pushing against that. Often the best answer to look at your simplest and most physical needs and take care of those, and wait for your feelings to catch up.
Sometimes there’s a degree of trial and error in finding out what you need to change in order to improve your energy levels on any given occasion. There’s no universal right answer here, and what you need may vary from one occasion to another. Even if you can’t pull yourself up, taking care of your most basic needs will give you the best possible resources to help you cope. Take it gently. Be patient with yourself. Don’t imagine you should be other than you are, and don’t feel if you can’t find a reason, there isn’t one. Humans are complicated things, and perfect self awareness in times of difficulty is ambitious to say the least.
