My dad died 2 years ago around this time. He was my best friend, and since he died I have felt incredibly insecure. I have never been single, and I rely on boyfriends for the self esteem boost I can no longer depend on from my dad. My boyfriend just broke up with me because I am too needy, and he is probably right. How do I learn to give myself the support I once got from my dad? I miss him so much.
