I don't know what to do. I really need help...please..?

So my husband and I will be married for two years come September 8th. We haven't really gotten a vacation we went to virginia for three days for our honeymoon and we have a infant that we haven't been away from and just can't do anything with each other anymore. I have PPD and a serious case of anxiety so it's hard for me to walk out of the house to even get the mail(mailbox in front yard) if our daughter is sleeping and i'm the only one home. I've had depression as far back as I can remember so it's nothing to new but when I had our daughter it just made everything worse. I want my husband and I to go to the beach we used to go every year in the winter before we got married and had a baby it's sp peaceful and romantic because for the most part it's just us there no crowds. Well one money is lately always an issue we have it so it couldn't hurt t go somewhere for a couple days but at the same time(anxiety) I don't want to spend it because I feel like we can send that money towards something else or IDK how my brain works sometimes so I think multiple things at the same time and can never cipher them to know how I really feel. because of PPD Mine and my husbands relationship has been beat in so much, but we don't let it (as far as we can help it) hurt in the long run because we know that arguing doesn't mean we love each other less it's just a release of emotions and we try and work on it. So my main question is what do we do i want to go away for a couple of days were it's cheap but worth it I'm not sure I can enjoy myself and I'm not sure if he wants to go and if he doens't what else can we do besides going out to dinner we can do that anytime we want when it doesn't mean anything besides time together, but this would be special so I want to do soemthing different. HELP. Thank you. P.S. Post-Pardum Deppression(PPD)
