negativity and sadness?

I often go through negative mood swings in a day which dont last terribly long, but i wanted advice on how to deal with it without upsetting the people around me

Go with your moods and don't worry what others think of them.

Yes but I dont want to ruin someone who I love and who loves me's happiness.

I read in a post, smile to yourself in front of the mirror daily.

You need to see if a distraction can help when negativity happens. A distraction could be a game here at PC, any game you have access to, music you enjoy, anything that you enjoy doing.

Try to think of reachable goals. For example, to clean up your room or one part of your room. When you reach the goal, think positive thoughts. If you do better in one day than another you get an idea of how you are. If you busy doing goal setting and reaching the goals, then you are occupied with the task at hand and you have passed that bad period very quickly.

Idk they are suggestions and hope it helps!

Dear MadHamlet,

I can relate somewhat.
Know you are not your emotions, your emotions do not control you.
First on how to deal without upsetting other people around you.
Do not be reactive to these emotions when around people, tell your self I am aware of the arising and will resolve latter.

Chart your day/night and find out when these negative feelings begin and make a note of time/place/who.
These are not long notes just mark the time of day or night.
Where you are (work, home, car, in a store, out in public)
And who you are with. You can name a person but it is the character or action of said person that is more important.
Example Sara is a manipulator. So just note Sara/manipulative. Joe may be angry person ect.
And with just one word how this person make you feel emotionally. anger, fear, anxious, sad, scared, ect.
Chart for a week or untill you can see a pattern and work with that.
Even just noting time and emotion will help.
