Guys, how do I stop getting exhausted so quickly after a conversation?

Help, i lose interest and energy while talking to someone new. Its gotten to the point where I'll lose my social battery in the middle of talking to them and ill slowly drift off to my imagination, trying to avoid our conversation because it gets too overwhelming. I wanna make new friends and sometimes I do make them but I end up slowly distancing myself, replying late, and Giving dry response untill they lose interest in talking to me. Its like I'm testing them but for what?? How do I fix this god awful habit? And open up to new people without getting so drained!!??
