Make a schedule for yourself and stick to it
You probably already get up, go to work, eat, and exercise, but perhaps your life could use a little more structure. The perception that loneliness will remain forever and that there is nothing you can do to remove the heavy cloud that hangs over your head is false.
It might be challenging to keep in mind that loneliness is typically temporary, so you need to keep a strict routine. When you "have a plan and a purpose", it's less difficult to feel alone. Decide to set an alarm for your morning meditation, your sister's phone call, and your face mask time. You'll feel more in control of them if you plan ahead. Once you've made a plan, try to follow it as strictly as you can. The organized routine will start to feel more and more natural, even if it may still be challenging at times.
