Recover from my eating disorder

i started eating large amounts of food and then purging myself in highschool. I am a freshmen in college now and thought that it might stop when i got out on my own. but it has only gotten worse. i wont to get better but can’t stand the thought of gaining weight. i’ve been to therapy and talked to family about it. my family is so worried about me and i hate to make them worry. i take it day by day. some days are better than others, but when i have a good day i try not to fall back the next.. it is a daily struggle and will be every day for the rest of my life.
