Life has certainly taken a difficult turn for you.
It would be easy to say that meditation is about being aware of just what is - so a noisy apartment should be no barrier - but I think that would go down like a lead balloon
Here's a few suggestions:-
I don't know if there are any quieter places around like churches or rooms set aside for praying - perhaps you could explore what might be around.
Wrap up warm and do a 15 minute walking meditation.
Take a mundane task that doesn't require much thinking about and really give all your attention to it observing the sound of it, the feel of it, the look of it, the rhythm of it.
If you can bear it you could sit and just listen intently to all the sounds you can hear around you identifying the near ones, the far ones, the ones that are continuous, the short sharp ones etc etc - this is also meditation - you may become aware of the silence these sounds exist in.
Hope things improve for you,
sending much loving kindness
