Is it wrong to celebrate Christmas as a Christian?

Im so lost. My grandparents don't celebrate christmas and so do my cousins and it sounds like their bragging when they say it. They are tough Christians and I decided to look more into it. Some people see it as a pagan holiday and others as a celebration to Jesus. Some see its as a marketing tactic. I had already bought gifts for people and (yes I know this was my problem) was more worried about gifts than celebrating Jesus. In future christmasas I will give out maybe a few gifts but not a lot (it is my sister's birthday) and focus more on Jesus. This christmas too. I just feel really guilty as a Christian and feel like I'm not doing what God wants me to do. I prayed to God that he will help me learn and become a better person but what if I'm missing the signs. Idk anymore. Please help. (Sorry if this seems all scrambled I'm typing what is going on in my mind)
