Advice....

I feel like I’m just alive and not living ... I don’t know if that makes sense I’m just so depressed , I moved across the country to be with my husband he just got back from deployment like 3 months ago and I’ve lived out here for a year , jobs are so hard to get , I’ve been doing online schooling and I talk to my bestfriend on FaceTime every night (she lives across the country from me) , I feel like my marriage is failing , he’s a great guy but something is missing and maybe it’s just because I’m in this weird state of mind ... I zone out all the time I don’t feel like I’m in reality .. a lot like a dream . I just literally drag through the day just to go to sleep. I feel like I have no purpose in my life and it’s really draining . I just don’t know what to do . Like idk how to make myself happy . I’m scared if I go to the doctors they will just put me on medicine and I really don’t want to do that .... does it get better ? Is this just a phase or is this how I will be for the rest of my life ? Advise please
