Grimes - Know The Way Personality Type, MBTI

Grimes - Know The Way personality type is INFP, and my Myers-Briggs is ENTP. I'm 22, and a recent college grad. I'm also a cat person. My hobbies include making art, reading, watching movies, listening to music, writing, and playing video games. I love cats more than any other animal. I have a brother and a sister. I love them dearly, and they are both very important to me. I love to read and write, and have been writing poems and short stories for as long as I can remember. I am an insomniac who has trouble staying asleep for more than about four hours at a time. I have anxiety issues, and I am constantly scared of losing the people that are important to me. I've been in therapy for years, and I'm learning how to deal with it on my own. I'm terrified of starting a relationship at this point, because I don't know if I can handle being hurt. I get really panicky when things are going well, and it makes me feel empty and useless if someone I'm close to walks away from me. What should I do?
