I know these are all sort of obvious suggestions but it's tough when I don't know what the exact issue is (but again, you're not obligated to tell me). The only other thing I can really suggest is actually talking to your friends and family members about it. I totally get the concern about being "whiny". I'm constantly worrying about burdening my friends with my problems but whenever I psyche myself up to do it, it almost always helps quite a bit. And more often than not, they'll be able to relate on some level even if they don't suffer from depression, which makes me feel less alone/like a weirdo.
I know you're younger than me and I've said this before but I've been comparing notes with a lot of friends lately and most are going through their own versions of midlife crisis mixed with "holy shit the world is a total mess right now", which is a ####ed up combination. I don't mean to downplay what you're going through but if you start talking to others, you may be surprised at how much common ground there is. Even if you're not an American, these are some dark ####ing times and everybody's feeling it to a certain extent. The 2 most common terms I hear people use to describe themselves these days are "overwhelmed" and "desensitized", striking the balance between staying informed and maintaining one's sanity. Seems like this is a conversation I have at least a few times a week. And of course the ####ed up state of the world is just gonna make whatever personal stuff you've got going on seem even worse.
All I can say beyond that is try to hang in there and keep posting these types of posts if you need to. It's not whiny, it's taking care of yourself. That's just the mental health stigma talking- if you had diabetes and needed insulin, nobody would call you "whiny" (well, hopefully not)
