I knew someone an college, probably another INTP, and she told me something that I've held on to "it's true that things won't make you happy, but people won't make you happy either."
That being said, I've put effort into improving my relationships with my family. A trick I've found recently is that I have just as much power over the quality of my relationships with someone as they do. I can feel myself slowly becoming a better conversationalist, and that's awesome. It just involves taking what seems to me like risks. Normal puts people to sleep.
