"Mental health service has been beyond poor"

I have been let down by the system and the people in the system too many times to the point I have now given up on it. in my last recent attempt at getting myself some help I had finally found someone who wanted to listen and took the time to talk to me on several occasions. I warned this person of my feelings getting low and they said they would look into arranging some therapy. however as I know this like the back of my hand they warned me of the never ending waiting list.

A few days after speaking to them about my low mood I attempted to take my life and was taken into hospital to be treated for an overdose. The following week after hearing nothing from my mental health team I receive a letter saying I'm discharged. I'm so angry and hurt that I care not to bother anymore.

My close friend recently killed himself by an overdose and he was in supported living and the same mental health team stopped supporting him too just before he took his life. I haven't seen the team even blink about how they treated him. Feeling low since then and then they do this to me. Anger and pain do not describe how wrong this feels.
