Do you always need some support in your life specially when you are a kid growing up?

i have never had support in my life since my mother died when i was 10, always was very insecure, got no love, could this be the reason for my emotional problems. i have been hurt in relationships too, because i always expected the care and unconditional motherly love from the other person, maybe becuase i never got it when i was growing up, iam 20 now and i really need to get rid of these emotional problems. Do you have any suggestions? I have been hurt a lot in my life by everyone my father, family, friends almost everyone. i prefer to be alone.
