So I've suffered with low self esteem and confidence for as long as I can remember growing up. I grew up with older twin sisters who were loving and looked after me - but of course they were closer to each other than with me so naturally I always felt like a bit of a spare part. During family gatherings eg with cousins I felt the same, as they were all a similar age to my sisters, so 3-5 years older. I always felt like the boring younger annoying family member.
This has stayed with me for as long as I can remember - I'm 24 now and still feel very awkward, self conscious and very sensitive at family events etc. I still always feel like a spare part. I never thought my relationship with my sisters was bad, until a year or so ago.
There's been two occasions where one of them got drunk and she hurled abuse at me, saying she didn't know me very well and that I've never bothered with her (I guess I've just always felt self conscious) and that I'm boring. She has said that I'm a psycho, abnormal, I "must be autistic" and plain weird. I have also been diagnosed with anxiety and depression, and she said I play on this and it's all an excuse. Both times has led me to sob myself to sleep. My mum excused it because she was drunk and she is just playing on my weaknesses, so apparently it's okay. Is this okay/normal?!
I guess I just want to know if how I'm feeling is normal or not. I have such severe self esteem issues down to all of this and still never feel comfortable or can be fully myself in front of my family, and feel I'll never have much of a relationship with my sisters, which is really sad. Any advice?
