One year later... rage and anxiety

Is it possible to have depression/anxiety stay past one year after giving birth? Can it cause irritability and rage?

Since I had my premature babies I’ve felt extremely anxious. I have struggled with wether it’s normal or not, given i had immuno compromised premature baby during a pandemic...

To add to it, where I live our government is quick to have us be in lockdown so I’ve spent more than half this year without my family/supports other than my husband who is also overwhelmed and struggling with anger himself.

(Side note: we try our best to give each other breaks however with his long work days, I often go weeks without going outside (due to babies health) and/or seeing anyone other than him, and we used to be extremely social prior to babies..

This feeling of rage appears so quickly and it’s new to me. I’ve never been someone with much anger in my life and never have I felt like being violent before (Though I obviously still don’t but I’ve never felt like punching a wall before, it started after having the babies and I assumed it would eventually go away once I started sleeping again but it hasn’t. ( And don’t worry, When we get angry we’ve always made sure to have the babies in a safe place if we need to walk away for a moment to cool down )

Given our current circumstances, I can’t get breaks from the babies other than 30-60 minutes every week or second week, other than that I’m always caring for them.

Im also thinking of getting a job again soon as financially we need a second income again, but I can’t imagine leaving the babies with anyone (the thought literally keeps me up at night when I thin of it). They’ve never been away from me other than a couple times when they were with my husband so far, and they don’t well when they see anyone other than my husband or myself (probably since they’ve hardly seen anyone else for months now).... but this makes me feel so guilty knowing the transition to daycare will be awful for them but not having a choice in the matter.

Anyone ever experience something like this before? Did it eventually go away/get better?
