I know how you feel!
A few months ago I constantly had the thought "there is no way out". Eventually I cracked and had a major depressive episode. But a hospital stay was really what I needed. Came out with an MDD diagnosis and some new meds. I'm still healing, and continuing to do so, but it was what I needed when I felt exactly like you do now.
I tell you this because I wholeheartedly want you to know that there is another way out!
Don't ever believe that no one cares about you...because we do! Hang in there, mija.
