Failed dissertation, ordinary/ non- honours degree need help

I’ve failed my psychology dissertation and retake. There’s multiple reasons for this, the pandemic, university being online for 2+years , teaching/lecturer strikes, financial issues mental health, lack of help from supervisor etc. But i’ve failed and i’m being told i can only graduate with a non honors degree as i’ve only achieved 330 of the 360 credits i need as ive failed my disso but passed everything else.
These past couple of years just seem like a waste of time and i’d always wished i’d pursued something else since starting uni. I know it’s not the end of the world but i also know my prospects decrease since significantly with a ordinary degree and that i won’t be able to apply to most graduate schemes.
Is there any advice anyone can give me as this is really affecting my mental health and i just feel so useless.
I heard some people mention open university and how you can transférer credits etc, but not too much else. How does this work exactly? Since i’ve failed only my dissertation would i have to complete another dissertation? Is everything online? Please help!! x

Two realistic choices. Phone the OU and talk to them, or get a job that isn't reliant on a degree. This is recoverable in the long term, but you need to crack on with something and not dwell. What career would you have had if you hadn't gone to uni?
