When you can't relax and enjoy life it can be a result of being overworked, having a stressful job or other stresses and worry in your life.
Not being able to relax and enjoy your life often stems from a habitual and deeply ingrained or even conditioned fight or flight response to stress, in which the nervous system is stuck in it's high alert mode as a result of chronic stress or past trauma or even high functioning anxiety.
Even the cultural pressure to be constantly productive as well as guilt over downtime, a fear of laziness or a need for external validation can also prevent the brain from allowing you to rest and relax, which can cause you to feel uneasy when you're not actively occupied.
The body's sympathetic nervous system is also conditioned to stay in high alert mode, which makes it hard for you to switch it off even when you're safe.
It is normal to not enjoy life as not everyone enjoys life.
Although not enjoying life, especially if it's persistent or a long term feeling or has come on suddenly could be an issue like depression, burnout or a condition called anhedonia, which is the inability to feel pleasure.
It's also common for people to feel joyless and unfulfilled, although it doesn't mean that you have to accept your self not feeling joy in life permanently.
Treatment, therapy and changes in lifestyle can help you become less depressed and start to enjoy life.
If you're not enjoying life, you may just need to try some new hobbies, go on a trip or even get away to another town and get out in nature for awhile.
I get to where I don't enjoy life and I change up my routine and will get out in nature and even plan a trip out of state to see some new scenery and I start to enjoy life again.
Being in the same location for days and years can get you to feeling down and seeing new places can get you out of that feeling of depression.
A key symptom of depression is a lack of interest or pleasure in activities that is often linked to brain chemistry imbalances of dopamine and serotonin.
Depression and lack of interest in life and activities can also peak in winter or when the days are rainy or gloomy
Stress and burnout, like from chronic stress from work or personal life or burnout from doing the same things over and over or being in the same location for too long can cause you to feel emotionally drained or numb.
Life also involves monotony and sometimes we as humans go through "meh" seasons or times where we fail to notice the positive things about life.
And constantly comparing your life to the curated and happy images of other people, like on social media can also make your own life feel unfulfilling.
If the lack of enjoyment in life lasts longer than a few weeks and or includes symptoms like appetite changes, sleep issues, sadness, lack of motivation or even social withdrawal it is also recommended that you see a doctor or mental health professional if possible.
To try to enjoy life more, focus on small daily tasks and movements, or if possible reintroduce a hobby that you used to enjoy.
Ensure you're getting adequate sleep, eating well and reducing your stress levels and get out as much as possible and change up your routine which can help.
