I think the lack of security in love and friendship is a very normal thing. Everyone will feel insecure. The important thing is not to let the lack of security affect the relationship between you and your lover and friends. Interact and strive to enhance your sense of security.
The reasons for lack of security are nothing more than low self-esteem, fear of loss and over-sensitivity. Low self-esteem makes you feel inferior to others, making you feel that you are in a weak position in a relationship. So you may feel that you may not be worthy of such a person, and you are not worthy of having such a beautiful relationship, so you will become sensitive, worry about gains and losses, and lack a sense of security.
Of course, the formation of a sense of security has a lot to do with the environment in which a person first lives, and is also inseparable from growth experience. More importantly, this thing seems to be transferable. If we are not careful, we It is easy to become a slave of "fear" and low self-esteem. Therefore, if you want to enhance your sense of security, you should start by changing your mentality, let yourself get out of your inferiority complex, work hard to make yourself confident, make yourself strong, and believe that you are "born with talents that will be useful."
At the same time, you must overcome the problem of being too sensitive when getting along with your lover and friends. Don't over-interpret the other person's behavior and actively communicate with the other person. When the other person's behavior does not meet your expectations, don't first think "he doesn't love you" or "he doesn't care about you". Maybe he just did it unintentionally. It's because he understands things a little differently than you do, he believes that he is worthy of being loved, and he believes that his lover really loves you.
"Others can't give you a sense of security. You can only give yourself a sense of security." Therefore, when you lack a sense of security in friendship and love, you should actively adjust your mentality, actively communicate with your lover, and believe in yourself.
