Why am I okay?

Past 6-7 years been depressed as hell and had severe panic attacks and been diagnosed for 2 years (bpd and severe depression). Been on antidepressants for 2 years but i stopped 4 months ago because i got overloaded with work and school so i would go about my days forgetting abt my meds. My psychiatrist recommended i take them again but i said i dont see the point anymore, my suicidal thoughts vanished when i woke up one day, i haven’t had anxiety about anything, haven’t had a panic attack in the last 5 months, and i generally feel okay and “happy” (idk im not really happy but im not depressed anymore). All of this even though im struggling financially and have debts as a teen and i literally have no time for anything other than school and work. At first i was scared i was about to have a psychosis episode or something because that’s what usually happens when you feel happy all of a sudden for no reason, but its been 5 months… I really have no reason to be happy and should feel super depressed, but im just neutral, like i woke up one day and all the negative thoughts vanished. Idk i feel super weird about it because ive never been a positive person, but im still weirded out by myself. Any of you ever experienced something like this? (My psychiatrist is still worried and wants me to stay on the meds but idk about that)
