Why my relatives & family members are unfriending me on facebook?

[ChOcoLaTe HoUse®]

I'm an introvert and i dont have talking skills like others. I prefer to stay alone... and also I dont have any job. So one day one of my cousin brother saw me online on Facebook & asked me why i dont talk with others (relatives & family) when i'm online.... & i explained that its not intentional..... because i hardly get online for just4-5min only.
Also they (my relatives) sent me invitation (on facebook) many times, to attend a community meeting held every month..... but i never showed up, because it was held in a different city.... where i had never been before.
So 1week ago when i changed my old profile photo, 6-7 of my relatives unfriend me in the next 3days. This new photo i uploaded is much better than the old one... infact it's my best looking pic till date (i also got many likes from college/school mates)..... but i dont understand why my relatives unfriended me. I feel very bad now.... because i never expected ppl from my family to unfriend me. And i think they hate me now. I dont know what's going on inside their mind. But i dont want to be outcasted.
Soo... what should i do to win back their confidence ?
