There can be a fine line between anxiety and depression. With depression you may feel anxious much of the time. With anxiety, you are not necessarily depressed. But anxiety left untreated can lead to depression. Depression is a black hole that traps your mind and body. Depression is essentially a form of withdrawal from life. One of its causes is suppressed feelings, which is true for anxiety also. Being stoic and refusing to let your feelings show can be very damaging in some cases. One of the treatments for both anxiety and depression is learning how to express yourself in a way that lets others know what you’re feeling.
We live in a society that says you should get to work and not feel sorry for yourself. Though you don’t want to wallow in self pity, you also don’t want to withhold your true feelings from people.
If you’re angry with someone, disappointed in a relationship, or feeling as if someone is using you for their purposes, it’s important to learn how to productively let other people know. If you hold all your emotions inside, they will bottleneck eventually and lead to anxiety and possibly some level of depression.
