Mental Breakdown

(Trigger warnings ) I had a mental Breakdown two days where I actually contemplated to off myself. I feel I am completely stuck in my current job and mental health has taken a free fall. There has been nothing to look forward to in my job career is absolutely stagnant I remember days i stayed up in night just ensure smooth deliverables but none of that translated to promotions or hike well I know you all will say why didn't you switch this is where the problem is I cannot bring myself to actually concentrate and prepare it seemingly a huge effort for me. I just not able to have that energy i feel absolutely negative. I could use some tough love. All I know is I cannot continue its literally do or die for me .PS : 2 days ago I "celebrated" 5 yrs work anniversary.
