please help - will it get better?

I haven't even had my first OB appt, it's in two weeks. I'm probably 7ish weeks. I've enjoyed nothing about being pregnant. I feel no excitement or connection, I cry all day, I sleep like shit, I have no motivation, my back is killing me, and I want to give up and sleep all day but I CANT because everything hurts so much. I know this is an all "me me me" post but I cannot find a way to get out of myself. I don't have a ton of money to throw at massages or things like that, plus I can barely motivate myself off the couch. I've worked hard in the past years on my mental health and know I feel like it's all gone down the drain. Idk, I'm just looking for support/advice. TIA
