Struggling to adjust to life with 2 kids

I have a 2.5 year old and a 6 week old and I’m struggling. As awful as it sounds to admit this, there are days where I regret having kids, days I regret having not just sticking to one kid etc. My 6 week old seems to whine constantly when awake and my 2.5 year old is throwing out screaming fits at the drop of a hat.

Does this get any easier? When? I’m not sure how much longer I can deal with crying from both children and not getting any time to myself on top of no sleep.

I don’t need any judgement from anyone, and I’m not going to do anything stupid. I’m just one mom admitting that this is so much harder than I anticipated and I need some advice / reassurance
