I have cousins ages 12 and 10... I feel nervous and awkward

I have cousins ages 12 and 10... I feel nervous and awkward around them, afraid of judgement...
Im thankful for my boyfriend because hes the only person I feel comfortable with but I can't always be with him;
It's frustrating...
Btw, I just want to know if this is social anxiety, Ill doubt it and think im just being anti social...

I realized I posted it under hocd aswell, but this is mostly just social fears, my bad

i struggle with some social fears too,
i always tought that i might have social anxiety but i don't know..it could be just low self esteem.
i really feel for you,we both struggle with social problems and hocd,
but don't worry there will come a time when you won't be like this anymore,but you got to make the effort,if you think you may have social anxiety then surround yourself with people,if you have a fear of being attracted to te same sex then face your fears!
we can't be like this forever,we won't be.
