First post and on mobile so forgive any formatting issues lmao

Everytime i get close to the end of something important i feel like i should bail and just drop whatever it is. Its with anything that even just feels important to me. Im about to graduate with an associates degree (i have 6 months left) and i feel like i should just drop out and leave, the same feeling when i was about to graduate high school. 
It also happens with things that just become big things for me, like i have so many unfinished video games, art projects, and writing things. Its like the idea of completing these things is super overwhelming and anxiety inducing.
Milestones in relationships also give me a feeling that i need to escape or just ghost my partner no matter how much i love them or want to be with them.
