You know where stopping with meds eventually leads. That's already taking a deliberate step from suicidal ideation to planning.
Meds are never perfect. (I do NOT want hugs for this; I am bringing it up solely for Nick's sake.) Julie's meds have needed adjusting four times in the last three months as different stressors have slipped her from overwhelming anxiety to suicidal ideation. She went to her person last night and had the dosage and type changed again, same as she would for any illness.
That's all it is, sickness. Yours is telling you to obsess over the past and a mythical point to life, and that if you can't sort those out, that's on you, except it's utter bullshit. Like allergies. Allergies tell someone that peanuts are deadly, and their body reacts by trying to kill them.
Our organs are dumb. The brain is an organ. Go to your psych, or check yourself into a place, and take care of this.
