Hi
If you try to control your emotions, you will become anxious, so it's not about controlling emotions, It's always good to ventilate in a healthy way. Being impulsive is not at all good for which you need some counselling.
Next Steps
as such it's not a serious issue, you can cope up, still if you want help you can visit any psychiatrsit or psychologist.
Health Tips
just take time before acting, everything will be alright.
all the best,
thank you.
