I've had them on and off. Mostly, they're related to being home bound with the exception of work and meeting up with friends about once a week. And seeing my bf of course, but we don't do much but watch tv and eat lately! Before I was working out every day, going and doing stuff all the time, always had plans, traveling a lot, etc. I don't have the energy for all that these days.
Also, I've been having difficulty sleeping and on those days, I actually feel less down. Because all day at work I daydream about laying down, and I'm pretty content when I can finally do so. Today I'm actually well-rested and because of that, bummed about not having plans for the next couple of weeks. We're going to go to a baseball game this weekend, so that's something.
Tonight probably just tv and dinner. And truthfully I don't want to do anything else anyway. But I'm still mildly depressed about never wanting to do anything! It's a weird conundrum. Also I don't really have 'shows' and I never know what to watch, because I never stayed at home before to get into anything on tv or Netflix. I always busied myself with plans with friends/family or managing my side 'business' (airbnb). I almost look forward to the stress of taking care of a newborn- I definitely won't be bored!
Re: Pregnancy blues
Also, you can always try inviting some friends over for a PJ night. Wear sweats & watch a movie, which will give you plans but nothing too crazy so you don't have to worry about expending all of your energy.
Hang in there & do your best to take care of yourself.
I don't want anyone else to be bummed but, I'm glad im not alone! A lot of times I just need to feel like I'm doing something/involved with other people/ and have something to look forward to. Planning more stay-in nights with my friends is a good idea.
