This will sound a bit strange, I know. I'be always felt a bit uncomfortable with my friends, even when I really consider them friends. Sometimes this happen when I am in a group, but (and this is the 'strange' thing, in my opinion) it happens expecially when I am only with one friend, even my best friend. In a group, if it's not too big and I know most of the people, I can feel comfortable because I don't feel obliged to say something or suggest what we could do...someone will do it however, and people could not notice that I am so silent. But when I am only with a friend, expecially if we are at my home, I feel that I should in some way 'entertain' her, suggest something nice to do together...but I'm not good in these things. And the more I think about it, the more I don't know what to say or to do and I feel uncomfortable. But o can't avoid thinking about it, and feeling that I'm not doing a 'good job'

For this reason I rarely invite friends to come and see me...and this, since most of them don't live in my same town, means that during the holidays I practically always stay alone. I'd like to see friends a bit more often, expecially my best friend, but at the same time I don't want to be in those uncomfortable moments. And I'm also worried that maybe they don't want to come, because I'm so boring

Maybe they are uncomfortable too with me. I don't know.
If it is for me, when I'm with a friend I find that it's nice also to just sit down together, taking a bit but not necessarily all the time, maybe watching some photos or other on our phones...like when we are waiting a lesson to begin. But these aren't very interesting activities, and I think that when a friend comes at my home she would like to do something more 'special'...also because when we ate waiting for a lesson we wait maybe half an hour, but at home we spent more time. So, when we are together and there is silence I immediately feel uncomfortable.
To say the truth, my best friend doesn't seem uncomfortable with me, and she seems happy when I finally ask her to come...probably it's just my problem. But it makes me suffer however.
Anyone has advices? Thank you in advance
