I don't feel like I can trust them anymore
Hi.
So I have this group of friends and we met in high school and we've been friends ever since which is about 6 years. We always got along and everything but lately I feel like I can't trust them anymore. I feel like they hide a lot of things from me, that they talk behind my back or when we go out for a cup of coffee they always give each other "the look" when I say some thing and they just start texting each other and we're at the same table so I know it's about me...
The thing is that when I'm with one friend at the time it's okay but if there's three of us or more I don't feel good anymore, I feel really uncomfortable and anxious. And those same two friends talk bad about each other when the other person isn't around or tell the secrets which I'd say she didn't want anyone else to know and it honestly really annoys me. We're 21 years old, they should stop acting like 12 years old girls... So I honestly don't know if I can trust them anymore because I feel like every single thing I'll tell to one person...that everyone will know. Because things I'd talk about I'd want only one person, maybe two to know. That's why I never talked to them about depression or anxiety or panic attacks.
And the other thing is that I have a cousin with which I get along really well and I went out with her friends...I felt better with them (I'm a introvert. actually I have ISTP personality type, and I'm really shy and don't talk a lot) and got along with them better. talked more that I usually do than I did with those friends which I've known for years...
I really don't know what to do... I don't know if I should try to fix it or leave them behind. But I don't know if that's a good idea either since I don't have many friends at all...
