Super embarrassing TMI-Smelly gas

For the past month or so I’ve been having TERRIBLE smelling gas. Like rotten eggs and just horrible smells. And it’s all the time... If I pass gas it is going to be smelly. Nothing at all in my diet has changed. No other symptoms at all. No new medicines. Literally nothing new! It’s becoming such an issue and I just don’t know how to handle it. Any advice? This is super embarrassing and I really don’t want to talk to my doctor because I feel like it’s gonna be a no big deal too bad thing and just a waste of time.
