Insecurity is the feeling of not being sure about a certain outcome. Insecurity is usually associated with the future. For example, you may be feeling insecure about a future aspect of your life or you may be afraid to lose something that you already own.

Feeling insecure in a relationship is a lot like a headache. Most of us experience the pain of it at one time or another and it’s curable once we know what causes it and what to do to avoid it. This pain is most acute in romantic relationships and they can really bring out our insecurities.

Almost everyone is insecure about some aspect of themselves. Insecurity comes from not valuing ourselves and then expecting someone else to value us. And when they don’t, our self-confidence plummets.

If the root of your feeling of insecurity is the lack of self-confidence, you don’t trust your ability to retain someone's love for a long period of time. You fear that your partner will suddenly decide to leave you. An insecure person needs reassuring all the time and that can really take its toll on any relationship especially a romantic one.

Feelings of insecurity in relationships results mainly from not being sure of one's self, one’s look or anything else the person considers important. If you don't feel that you are good enough for your partner you will always worry that he or she will be looking for someone else to replace you. This will turn you into a needy person to such an extent that, eventually, your partner will hate you. If this happened then you are unintentionally making your worst fear come true.

One of the strongest reasons that can make someone distrust their abilities is the feeling of inferiority. People who suffer from the feeling of inferiority will experience insecurity in their relationships. And it’s only through dealing with their inferiority that any insecurity they feel about their relationships will disappear.

If you were rejected more than once in previous relationships you may start to believe that you deserve to be rejected or that there is something wrong with you. If this is how you feel then your goal is to get rid of such false beliefs by realising that there are hundreds of reasons that could make someone reject you and that it has nothing to do with you.

There may be other causes to your feelings of insecurity, however, they will always come down to one thing: not being sure of your own abilities. In general you should try to identify the one thing that makes you unsure of yourself the most and then take actions to build confidence in that area. In order to deal with your feelings of insecurity you must fight the root cause that made those feelings of insecurity appear in your life.

Ignoring your problems and allowing them to accumulate can be the primary source for depression. Some people face their problems squarely as soon as they encounter them while others bury them deeply in their subconscious minds or throw them behind their backs. When they do so their subconscious minds usually respond back with depression.

If you didn't take any actions to deal with your feelings of insecurity then surely you will end up depressed. Depression results from ignoring an issue that is important to you instead of taking an action to resolve it. Never ignore a problem and start dealing with your problems right away.

Feeling insecure in a relationship is not a big issue. If the proper actions are taken; like committing to improving your self-image and building your self-confidence then your feelings of insecurity will fade away.
