Does it really get better/easier?

My girl twins are 11 weeks now. People say it always gets easier but I feel like it’s been harder lately. Even with help from my husband’s family I still feel like it’s hard mentally and physically. At the end of the day I am so worn out. I’m just wondering if it really gets easier? Don’t get me wrong, I love them so much and definitely have moments where I enjoy them. But most of the time I feel like I’m fighting to survive. Idk, maybe it’s ppd too? I’m trying really hard to stay positive and keep going. So parents of twins who are older than mine, does it get easier? Maybe I’m just looking for encouragement..
