Ask HN: How do I deal with the stress of fundraising?

Hey, my co-founder and I are trying to raise a a seed round for a product that has shown some traction (200+ paid B2C customers).

Both of us are engineers, and new to fundraising. As the relatively less introverted one, I'm the one in charge of the conversations. Not that I'm any good at story telling, but I'm getting better with every subsequent pitch.

The experience so far has been brutal. There's a constant stream of negativity to deal with. We wake up to rejections, get ghosted by those who showed genuine interest. To top it all off, we have to keep a straight face in front of our team to hide the pain of someone not seeing the value in what we are building.

My question to HN is, what can I do to make this process less emotionally taxing?

Thank you! :)
