How do people stick to being optimistic?

I’m typically a very optimistic person, but sometimes I can have my breakdowns (like I’m having right now as I’m typing this). So, I wanted to ask, HOW THE FUCK DO PEOPLE STICK TO IT EVEN WHEN LIFE CAN REALLY SUCK?

i mean, you cant always be happy and optimistic. i think just letting yourself feel negative emotions when they come up and acknowledging that it's okay to feel them genuinely does help. i try to be positive and i make sure i put time into the things i care about, but sometimes life can just be shitty. the world isn't in a great place and it's normal to be aware of that but i think as long as you remember the things that make you happy and make sure to keep those things in your life, it'll be fine. no one's happy and optimistic all the time 

im generally quite optimistic myself and honestly keeping it up destroys me, people rarely ever see me express anything but happiness except online when its easier to say what i feel. I don't really have very great advice but i've found in getting better that letting yourself feel things helps so dedicating some time for yourself to feel your emotions and let them out could help. and honestly being optimistic all of the time is overrated, letting yourself be you is worth it and life can suck but remembering there's a tomorrow that could be better makes me pull through. you're doing great <3

If you don't let yourself feel negative emotions they will just stay. Have a mental breakdown so that you can go back to being happy; Idk if it's just me but i feel a lot better after crying for a whole night (although as of now I'm a pessimist, i used to be a realist but stuff like this changes). You shouldn't really force yourself to be something you're not if the situation doesn't call for it- if you're happy to help others that's fair but if you're all alone you have the space to be authentic to how you feel and you shouldn't disregard that. If you're being optimistic to keep yourself sane, clearly it only works for so long and you may need another strategy alongside it. 

lie to myself until I forgot I'm lying to myself, especially when it comes to how shitty academics are for me rn lolz
