Teen mom in need of advice HELP

Hey guys, so I decided to reach out to the glow community because lately I have felt like there arnt many other people I can reach out to. I am 18 years old and I am 18 weeks pregnant. I have a wonderful fiancé who’s been working 5-6 days a week because I have been on temporary bed rest. I have started to realize spending all this time alone I feel like there is nothing for me to do. I sit on the couch watching tv just day after day. Maybe I take a nap or maybe I sleep till noon. I worry as some one who as suffered depression in the past its starting to creep back up. All I want to do is sleep, I’ve lost all my creativity (I used to paint and write weekly), I’ve felt lazy because I am not able to work out. I’ve felt sick and stuck in this slump I don’t know how to get out of. I really don’t have any friends and all my family lives in other states. Has anyone felt this way? Does anyone have any advice on how I can start to feel like myself again?
