Your statement is heartfelt and conveys your feelings beautifully. However, there are a few minor grammatical adjustments and punctuation changes that can enhance clarity. Here's a revised version:
Dad, thank you for being the father I always wanted. Thanks for loving me and helping me grow into the person I am today. I am so proud to be your daughter/son. I love the guidance and respect you taught me, and I will always look up to you. Most of all, thank you for just being my dad. I love you lots, and may you have many more years to come. May God grant you the best in this world, and may you always prosper.
Feel free to use this version or modify it further to better match your own voice!
