Is it really hard being a father ?

When i met my wife all what i was thinking is how happy i am for spending my time with her, no responsibilities, no hard thinking, it was all about happiness that i was missing my entire life.
After all that time together we had our baby girl and it was the most weird feeling could anyone ever feel.
Am i really a father now?
Am i responsible for a new born child?
Is that how should i feel now?
It was really scary for me, but now after year and a half i knew it, the best thing ever happened to me was my baby Syna.
She took my heart, my life, my soul and every single part of me now belongs to her and i am happy with that.
