What should I do when I'm depressed?

Indiehackers is not the right place to seek answers for depression. Go visit a doctor and take it seriously.

Please seek professional help. Many will suggest different things. But seek advice from someone qualified to give you advice.

I've found that improving and working on my physical health has a major affect on improving my mental health.

Going on a walk outside in the sun, moving my body helps me...personally!

But also echo'ing the folks here who are advising to talk with someone and taking it serious.

I love the honesty and willingness to be upfront. Depression is difficult, especially when you're running your own business (double so if you are a solo-founder).

As the two previous comments suggest, you need to work on yourself first and foremost.

Get out of the house to refresh your mindset, go somewhere secluded and disconnect so you can think about what it is that's troubling you.

You'll also want to find out what the exact source of your depression is. Create a spreadsheet and write down the feelings you're having for the day, you may be able to spot a trend, and once the trend is spotted you'll know exactly what you need to work on.

You got this!

You need to find out the cause of your depression and work on that. If that's connected to something you've been doing but couldn't, try harder, remain focused and believe in yourself.

I would be out of my depth to provide direct advice as I'm not a professional in the space.
However it's important to know your type of depression before trying to ask advice or find a solution.
E.g. severe clinical depression is quite different to other forms. See: https://www.medicalnewstoday.com/articles/314698
Hence the best advice/treatment for each type of depression is different.
Having a chat with a professional therapist can't hurt. Best of luck in getting through this.
