First of all, flag this with google. It's important they know what's going on here. It can be a bit tricky as they will almost always suggest going through FAQ's (frequently asked questions) and it takes a while, but get through to someone, and just let them know all of this. Next, when a device logs in to google, it's IP address is stored. So if another device is being used to access your google account, then it means they can be tracked and identified, and you may be able to see what devices are connected and where, and remove them. Just take steps right now, to have what we call two factor authentication with your phone number. Make sure that is enabled. That way, only someone with your phone number can make major decisions and changes on your account, and so even if a hacker has access, they can't do anything without your actual phone number. Set it up so it only works for your phone. So, to summarise, remove that phone number from your account, add yours as part of 2 factor authentication so only someone with access to your phone can verify changes and not some other number, and then you need to report this whole situation to google. The sooner the better. Also see if you can look on your account for a list of new devices connected to confirm your suspicions. And if there is any hint of payments being made on things like subscriptions that you don't know, inform your bank, and the authorities (the bank may do this for you). I know this is very scary for you right now, but you can get through this.
