I didn't realise it at the time, but one of the best side-effects of being part of an accelerator programme is the comradery you have with the other teams.
Although the programme itself was helpful in organising our business, and I wouldn't trade that experience for the world, the follow-up meetings we have once a month (founders only) have been a godsend for our collective mental health. Just being able to speak openly and honestly about the day-to-day struggles is hugely therapeutic.
I'd highly recommend finding a few other founders you can meet with on a regular basis and discuss your trials and tribulations. We're based in London but I'm sure there are some people you can find near you.
Good luck and keep your powder dry!
