Maybe bcuz yu feel as if ur missing something in life... Or some unresolved problem that still lingers and bothers yu at random times keeps making ur moods change. Maybe yu should talk to someone professional and see what they think.. Or yu can js open up to a close friend or relative and tell them what goin on and they cAn help uu over come these random mood swings... Hope I helped :) :)
Meaby those random times remind you of something, sometimes I can be sitting somewhere, doing nothing and I see something that makes me think of a sad thing so I get sad. But then again it could be that you might have depression, or it could be as simple as the fact that your growing up and the hormones are acting up. Meaby something is not going to well in your life?
It could be many things Depression, Hormonal, Bipolar etc. etc. Sometimes it just happens due to chemical imbalance....Hope I helped in some way :)
i am like that t.but i was diagnosed with sever depression two years ago and i take medication for it.
I get that,it's sorta like from happy to sad mood swings.I suffer from depression though.
I know I'm not bipolar.
