For me, a lot depends on sleep and energy and my... sociality? haha. That's not a real word.

Hypo: Very little sleep (often forgetting food), loads of energy, and I will want to be out drinking/partying on the weekends and will want to be out a lot during the week. I also get more motivated to start new hobbies. I'll drink to excess, but not out of a desire to forget - I'll just be bubbly and happy and go along with everything, and that tends to involve always having a drink in my hand - but I'm a quick drinker and don't pay attention, so I'll forget to count my drinks.

Normal: Fairly average sleep, am happy to be out on the weekend and some things mid-week but whether they're chill or party-like is fine with me. I'll enjoy doing whatever. I'll be remembering to eat and get back to eating healthy.

Mild depression: Will be pretty consistently tired, not as much energy. Will still go out to social engagements but might cancel and will not want to be out late or doing anything that's really party-like. I'm more likely to want to go out for a meal 1:1 or something. My eating will be cheap foods because I won't want to put effort in to cooking. I might be lucky and get mild enjoyment out of some things, and will stay at home as much as possible - but might feel better with that and will engage in solo escapes (reading, gaming).

Moderate depression: I will almost always decline invitations unless I really feel the pressure. If there is a chance that it won't be 1;1 I will almost definitely not go. I'll miss meals because I won't be hungry. This is when I will really start with oversleeping. Even when I'm home I won't really do things like read or game, and my online social engagement will decrease (I won't want to write in forums as much). I'll sometimes think that death would be a good idea right then. My apartment will probably start to get messy as I will slack on basic chores.

Major depression: Well, this one is obvious as I start daydreaming more about suicide and wish that I could indulge in that. I will completely hermit and will NOT go out with people. I can still pretend that I'm in a moderate depression though - so I can still get through work. But ALL of my limited energy goes towards work. Chores at home will pile up. Aside from doing the dishes when I have to, and taking out garbage/kitty litter, everything else will go on the wayside.

Panicky/stressed: This can be present in any stage, but usually it will get mixed in with depressions and I consider it separate as it may or may not be present. This is usually what makes me cry. I'll flee situations if I get freaked out, I'll get angry and frustrated with myself, I may get snappy at someone if they catch me in the wrong moment. If I am like this in combination with a moderate/severe depression, this is when I end up with a mild OD as I will be in too much pain to handle things so will swallow enough pills to give me a stomach ache as something to focus on. This is also when I will drink to the point of throwing up (still a rare occurance) because I will be drinking to knock myself out or to forget.
