The most difficult emotion to control

I voted embarrassment - I'm pretty well known for being extremely even-keeled, and my calmness in the face of, well, just about anything gets noticed. If I'm likely to get noticed for anything other than apathy, it's probably going to be when I'm embarrassed.

Anger...by a landslide, lol. :c

Everything else I've got decently well under control other than crappy self esteem lol.

Anger by far. I can only do so much to hold it back. If I'm in the presence of someone who does make me particularly angry, I can't hide it.

Anything else I can usually mask pretty easily.

Good question, which I hadn't considered until now.
I would have put down anxiety, but it wasnt an option.

Desire...when left uncontrolled can lead to problems, but when I've been able to rein in desire to just inspire level, it has good results. I can pursue doggedly, when inspired. The dreams I've been given when I've been able to control desire...just fall into place.
Desire is tuff to control though!

For me it is not on here, which is why I did not choose one of the options. It would be despair. It is not very noticeable, but for me I find myself moving in and out of it pretty regularly.

Panic (fear) is the one I can't control, if it builds up to the point that I freak out. Which doesn't happen any more with the meds I am on, and if I manage how loud things are and who and what I am around and make sure I don't get pushed beyond what I can process without down time. But when I get scared enough, I will scream my head off (it's happened before). It's embarassing, and even if it doesn't get that bad, walking around in circles and doing other rhythmic things tends to make people think you're a lunatic. Luckily I have only gotten to that point maybe 4 times in the last 6 years, but I still tend to get nervous and hyper and have trouble being calm and speaking slowly, paying attention and noticing things I should notice (like traffic). Fear is definitely the worst one for me. Everything else has never gotten to the point where I couldn't control it.

NO LOVE

I would vote love since you just don't control it, there is no stopping it, the other emotions you can at least have some influence on yourself. So I did not vote

I can actually control all of these to a certain extent, but happiness is what gets me all the time. Because I don't exercise control over that particular emotion, I can hardly control it at all.

Fear. Super hard for me to control.

I'm fairly good at keeping most emotions in check, except anger.
It nearly always leads to something awful if I don't deal with it head on asap.
