Help why does my mood change?

Always get a change in my brain function. I sometimes feel happy and like i understand everything. Sometimes i feel like i've been defeated as soon as i fail to achieve something like fix an object. In the night i get huge mood swings (example-i want to make everyone i know happy, i want to fix the world, i want to be nice, and or even things like become a doctor, make friends etc. )the next day i feel normal and then i think back at how stupid i was last night. BTW i dont socialize a lot only have a job and not much friends. Could this be the problem, oh yeah and i am also gay. I always tell myself that i going to come out which would make it easier for me but i dont and next day i hold it in. Then i tell my self i might get depression or something. Anyways is it because i have a lot of free time, should i tell people im gay, should i make friends, am i bipolar, or what...Help why does my mood change?
It doesn't sound like your bipolar. I think you're just concerned/afraid of people's reaction if you come out, maybe you want people to know the whole you but you didn't find the right moment to get this off your chest :)



Apart from this, mood changes are normal. I also have a lot of time to waste and the tiniest daily events annoy me, an hour later I'm having loads of fun, later I come home and I become sad (thinking something like: no future, no money, no perspectives :)) )Help why does my mood change?
Well u could be bipolar or it could be just part of your personality. Some people are just naturally more indecisive or moody than other people. I think you should maybe confide in someme that could help you, like a parent, friend, or psychologist. Coming out to some of your close friends might help relieve the stress if you're ready to come out.
