Struggling with offers

TLDR: Am I alone feeling like this? Or am I just overthinking it. I feel like something may be missing even though I feel like I’m in the right direction. I felt an overwhelming pull to make an altar to Lord Apollon some time ago, I did, but I’m still not sure if I’m doing it “right.” I’ve been told time and time again that it is based a little on “feeling.” Now, I have no doubt in my belief of the Gods and Goddesses, but I feel like I’m giving offerings wrong or something of the sort.

It’s usually a cup of water or a cup of wine, and tonight was a fresh peeled and sliced orange with a glass of water. I know I am to offer what I can provide more or less without strain of me acquiring them. Though, I’m not sure how to “properly” pray other than something along the lines of “I offer this to you to show my appreciation and devotion—“ etc etc to go with the offerings. Though I feel warm and that I am at least trying to do good by it, is there anything that I’m missing? I take an incense around my room before anything, I wash my hands, I light a candle, and I simply smile feeling like I’m pushing forward, but something feels missing after I give an offering sometimes.
