Does anyone else feel like they're not in control of their wedding planning?

So my FH and I have been engaged for 1.5 years now. Originally we were planning to do something small but I have a big family so that was kind of hard to do. We got our list up to 85 guests and found a restaurant we both love, with great menu and reasonable price and I left the deposit and everything. It's also very convenient because it's only 10 minute drive from the church we will be getting married in. Yesterday I announced to my immediate family that we booked a venue and then my brother, who works in the restaurant business (but never before offered anything) tells me that why didn't I wait that they're opening a new restaurant in 3 months and that we could do the reception there, that he will be able to get a great deal and he offered to pay for it. Then everyone starts criticizing me and telling me what to do or what I should do. So now I cancelled my original venue which I loved and was so convenient and now will wait until the other restaurant opens and have the reception there. While I am extremely grateful and lucky that my brother offered to pay for it, it's just really inconvenient because this restaurant will be 40 minutes drive from our church. And now I just don't feel excited about my wedding. I'm looking forward to the church ceremony but not looking forward to the reception.
