Why do I get uncomfortable from love?

There could be several reasons why. You don't appreciate others caring for you, you may had never been loved enough growing up, you have anxiety, you are introverted. There could be several reason why. I never treat someone poorly, yell or become sour when they are trying to show their consent and love for me. Part of what makes life meaningful (to some), is to be loved. I personally, tend to not understand how to communicate with those expressing feelings and it has made it very hard to communicate with others. My mom hardly kissed, held and hugged me and when she would express those loving feelings she often would be yelling in anger (she has a personality disorder which can cause random outbursts of anger) So when I am loved, kissed, hugged by family it tends to make me feel undecided and unsure of trusting them, for fear I will get hurt and that can make anyone who has grown up in a struggling past sour and eager to be alone and excluded from others. I am currently learning slowly, how to handle these feelings. I am currently with my partner which allows me to grow from this.
