Feeling regret, and depression....

I haven't liked the name we picked for our son since he was three weeks old. We picked it on a coin flip becsuse we couldn't pick and we tried to pick another name to change it at 6 weeks old and we didnt. We decided to leave it and that was that. I was fine for awhile and now it's really bothering me again. He's 14 weeks old. It's causing me some serious issues and I just cry about it. I don't know what to do. I know it's too late but it makes me so sad and idk why. When I hear people call him by his name it makes me cringe. How do I get over this? (I've tried finding a nickname and there aren't any or nobody listens and uses it) I really just need to let this go and I can't.....just needed to vent. If I tell my husband he will probably lose it or leave me Becsuse I've let it go on so long now.
