I don't know how to make friends and I feel like I've lost all the ones I used to have.
Are you looking for a certain type of friend?
I want to know how to make cosy friends.
Sometimes we lose friends as we get older. You should seek out the type of friends you want by meeting new people.
If I find someone similar to me, I'll of course be cosy with them and be able to relate with them.
That is good that you want to make new friends. As we grow older it's understandable to lose some friends. We make new ones as we grow up and move on.
