needing advice please 💞

I have an appointment with my OB on Tuesday. My boyfriend recently left for the airforce and we are expecting our first baby. Ever since he left I’ve felt so down, alone, and sad. I’ve cried so much and just want him here through this. I have a huge support system and family, but I just feel so alone without him. Should I bring it up to my doctor? I don’t want to feel like this till he gets back... I’m usually sooo happy all the time and now I just feel so sad and wanna lay in bed all day. It sucks so much feeling like this and I just want it to go away.
