Hi brokenentity, lets agree to downgrade those concerns about your appearance for now in exchange for the depression, hey??
At times (maybe a lot of the time?) you're feeling so drained, empty, lost, lacking the energy to even show much of an interest in your appearance and it's so not simply a matter of you not "pulling yourself together".......so you're probably not going to look "great, great, great" are you
So please don't allow this to give you another reason to feel bad about yourself, you have a very good reason you're not looking your best.
So maybe first and foremost trying to put any energy you have into tackling the depression?? I know you might already be trying to do that anyway but...........
If setting yourself small, managable goals might help you might even want to make one/two of them around self care, but whatever they are even small things are going to be an achievement, right??
But sometimes talking can help too of course........if you have a T, if you have friends...........and to us??
I know there are no "easy answers" but one step at a time, hey??

And just a couple of other things:
I've got to say I'm really sorry about the way you've been treated by others, you know it says way more about them than about you, hey??
If people are treating you like that you so DO NOT want/need to be taking that on board right now, you've got enough to cope with. Allow the way they're behaving to be their problem.
And your appearance..........well obviously as the depression eases a bit some aspects are going to come back, they're not lost they're just masked right now.
But in other ways, there's nothing wrong with looking a bit older (time has passed, hasn't it?)
You might look different..........but there can still be a good different, you know. Looks can be so subjective. What looks not so good to one person can look the complete opposite to another person and vica versa.

So back to the depression.............??
I know it can be so hard, but you're not on your own, we're here for you
