Ive recently been having some good coversations with my housemates and have been managing to open up quite well to them. When im a few minutes into a conversation that is going well i feel a lot less anxious, can think of things to say quite easily and start to enjoy the coversation. However, the next time we speak i still feel really anxious starting conversations and during the first few minutes of conversation. I know im capable of having a good chat with them and even though i know i can feel at ease around them i cannot stay in this state of mind. I seem to automatically switch back to my nervous self after the conversation. How can i stop this?
