Advice or support

My partner is leaving to the military and I most likely will be delivering a baby alone simply because family is not an option and I live far away from family and I’m not so best terms with mother in law and I’m reality my partner is the only one there for me but he’s going to be away maybe 5 months ..... I planned to get on depression pills (I been diagnosed with depression) but my partner always seems to know how to calm me and help but now when he’s gone I’m afraid. I have two puppies but it doesn’t feel the same .....
