How do I help other people understand that my sadness is not their fault?

Try talking about it with them, telling them how you feel and why and letting them know that you feel that they've got nothing to do with you feeling that way

Sometimes it could be so frustrating to actually convince other people that whatever it is that we are feeling, is not their fault. It would even add to our sadness knowing that people are affected by our sadness in a negative way. So, I think, it is best to NOT SHOW that we are sad. I don't mean to keep it bottled up inside-- no. I meant to not display our sadness or negative emotions but channel that emotions to something else. Write, draw, listen to music or whatever that help us to calm ourselves and release some of the emotions that we have.

I always thank them for being with me...that makes them feel that instead of causing pain, got rid of some. Say thank you.

First make sure you do understand that your sadness is not their fault. If that is clear to you rest will be pretty much easy. If someone feels that your sadness is due to him/her, then it means he/she cares about you a lot and he/she feels that he/she is not able to make things right for you. Just sit down with him/her on one fine evening and let a free flow of chatting in between you two. Make him/her know about the situation and that he/she is completely aware of it. Then things will automatically turn right.

Explain to them clearly that's its not. Tell them the reasons why you;re sad then make them see that your;re sad for other reasons

You just have to speak up. But maybe it is their fault. Who's to say? This world is full of rotten people and you are responsible for your own happiness. Tune in, freak out, get beaten. But most importantly, survive

Explain to them on full lengths on why exactly you're sad, they may be able to help too, so win, win.

Maybe an indirect approach would be a good idea, try to show them that you really care about them and you still love them, this way they'll understand that they're not the cause and you really don't blame them. But i think the best help would be just trying not to be sad in the first place :)

I usually give them links to webpages or send them infographics about mood disorders. I tell them that it is not their fault - it is the fault of the chemicals in my brain. Contrary to what they think, they are the ones who are keeping me from feeling even sadder!

Just explain your situation as much as you can and repeatedly assure them that they have nothing to do with it
