Becoming increasingly irritated.
Getting frustrated or irritated is a normal part of life and it can be a response to stressful situations. However feeling irritable all the time and especially to those closest to you could be a sign that you need to get away from every one for a short while. Sometimes something as simple as going for a walk by yourself can make all the difference.
Not getting enjoyment out of things that you normally would enjoy.
Having a hobby is a great way to add fulfilment to ones life but something that previously gave you much joy that you feel unable to engage with could be a sign that you need to take step back.
