So I've been tracking my mood with apps and I realized I'll have a few good days, I'll feel optimistic and then I'll have a sharp decline in mood. It's like day and night. When I'm down I'm extremely down. Splitting on my partner, suicidal thoughts, deep depression, pushing people away, even splitting on friends, not wanting to go out and staying in bed etc. And i can't figure out what causes it. Sometimes i can link it to a certain event but usually in my better days i would be able to handle an event like that. So even though throughout the day my moods shift fast as well it isnt as intense as this. Does anyone else experience this? Its like 2 steps forward one step back every time.
