Yes it is but emotions are not always logical from ruminating the past or problems overreacting and misunderstanding situations. We can get over anxious and blow up everything in proportion and destroy relationships.

Our negative emotions can cause us to be negative to be around. Often we can stay too long in the negative emotions that it's hard to build positive relationships.

We might also solve our problems with our emotions and that might not always be logical. For example, to feel better from our anxieties in uncomfortable situations, we might become an emotional eater to help us feel better and lead to food dependency.

Our negative emotions can do a lot of damage in relationships, choices we make and preventing us from achieving our goals. For example, we can feel too sad and causes us to lack motivation to do our work and do a decent job.

Our emotions can cause us to ruminate too much which can make us upset, make us forget other things like turn off the stove or misplace our wallets.

That is not to say all emotions are bad. Some emotions are good, such as feeling fear when real danger is approaching and taking the appropriate actions to avoid danger. And happy emotions can helps us feel connected with love ones and help strengthen relationships and create happy moments and memories.
And when you are happier, you can be more positive and be easier to be around.
