Hi hidesad, if things aren't going right for you/if things haven't gone well/if you would have preferred to do different things or more in some situations...........that doesn't need to make you a loser
With depression sometimes it's about doing the best you can do and it's completely understandable if even that is really hard, let alone managing to do things you would have done without depression.
So bear in mind you have got a lot to cope with and try to "give yourself a break"/don't be too tough on yourself/don't hold yourself up to too high expectations.
It's not you failing at all, it's the depression holding you back and that isn't your fault.
So when the memories come remind yourself of the reality of the situations..........e.g. you did all you could..........
And depression can be really good at masking/hiding/downgrading any achievements/any "positives" in your life too, so maybe worth trying listing/focusing on them as well as far as you can???
I know it can be real hard though, so go easy on yourself
