Pregnant and don’t feel like myself

Does anyone else feel this way. I’m currently 14 weeks pregnant. And since getting pregnant, I havnt felt like myself. Not the usual nausea, exhaustion ect (which has been horrid) but as in yourself, I don’t feel like me, I’m anxious all the time, nervous energy yet no motivation, don’t enjoy my usual relaxing activities. I have 3 other beautiful children so it’s not my first pregnancy and I’ve never experienced anything Like this. I’m scared I’ll never feel like me again. Has anyone ever felt like this? Do you ever feel like yourself again? I’ve been seeing my gp and a mental health team about it. But it feels different than my usual anxiety. I feel like a ghost in my own body. Empty.
