I'm 25 and married, my daughter is turning 2 tomorrow. Is it hard at times? Absolutely!!! Is it worth all the work, sleepless nights, sleepless flights and restrictions on my life? 100% for sure!!!
I don't say she makes my life miserable, and not only because I don't want to sound ungrateful, or like a bad parent. Because she doesn't. I'm happy to travel less, sleep less, and have restrictions on my life, because I love my daughter, and can't imagine a life without her.
If I had feelings of misery, or trouble coping I would seek professionall counseling or assistance. There is no shame in admitting to yourself or others that you are challenged by raising children. There are so many other high stress things that can be going on, and it's only natural to feel overwhelmed. Health issues, lack of sustenance and financial instability, marital strife, add hardships in child- rearing to any of those and lots of people would be overwhelmed.
Please take my advice, if anyone is feeling oberwhelmed about anything, seek guidance, advice, assistance or counseling from a professional, or someone you trust and are comfortable with. There is no shame, or reason to feel guilty or inadequate.
I will admit that all the props go to my wonderful wife. Without her I would be unable to raise my daughter, and would probably be a huge mess myself.
