The thing is that I am a shy person, I almost always feel nervous when I interact with other people other than my close family. I just don't know why that happens to me. Today a friend of mine is coming to my place to give me a birthday present (my birthday was on wednesday). I don't usually invite people to my place, but this time I accepted because I thought she would only give me the present, maybe talk for 5 minutes or so, and she would go, but apparently she pretends to stay a little bit longer than I thought. I normally feel nervous just because of interacting but now I feel even more nervous because it is going to be in my place. It just feels a little uncomfortable for me. Besides, tonight I will hang out with another friend (a girl as well), with whom I have had a couple of sexual encounters before. I don't know but I can't stop feeling anxious because of these two interactions. I don't know why I feel like this and I don't know what to do about it. I can't even do my homework because I can't stop thinking about this and feeling this way. I just hope it goes well. I need some help.
