tw- my newest problem behavior

my roommate has diabetes and pricks her finger every day to check her fasting blood sugar. i asked if i could try it (using a new lancet obv) and my fasting blood sugar was 91. hers was actually lower than mine and she has type 2 diabetes and is overweight. idk why but that triggered tf out of me bc that apparently that isn’t even considered low. i always blame my shakiness/dizziness/crankiness on low blood sugar but that’s not true. i ordered my own blood sugar testing kit from amazon and ive been checking it every morning and its worse than the scale. im in for a deep relapse this witer :(
