i’m so tired of my mental illnesses

so about a year and a bit ago, my psychiatrist diagnosed me with borderline personality disorder, two types of depression, thee types of anxiety (ocd social anxiety and general anxiety), and also autism. i’ve been trying very hard to not let my diagnoses “define” me like everyone tells me, and to not be a victim or whatever. but nothing is helping and nothing has ever helped. i’ve tried out like 4 medications for depression, and two for anxiety, and none of them helped. i’m so tired of all this and i don’t have friends or anyone i could talk to abt this so my loneliness is like through the roof rn and im just so tired of everything
