The warmest of welcomes to you 🙂
It can definitely be tough, gaining an accurate sense of what we're feeling at any given time. A general sense really doesn't help pinpoint what challenges can be at play.
Personally, I've found there can be a variety of lows under the headings of physical/chemical lows (including deficiencies or imbalances, for example), mental lows connected to belief systems, a lack of mental stimulation, certain inner dialogue etc and then there can be what I'd call natural lows that can come with a lack of inspiration or can come with a sense of 'twisting in the wind without any sense of direction'. What all can have in common is low energy. Hard to feel joyful or excited when we've got next to no energy running through us with which to feel joy or excitement through.
The jittery feeling's an interesting one too. Such a feeling can also relate to a variety of things, such as stress, frustration, an agitating need that's demanding to be met (such as maybe some new goals that need to be set and worked towards), a sense of other people's stress or upset, growing intolerance, a nervous system that's needing attention and management and the list goes on.
Can be hard to put our finger on things, especially if we're not in the habit of dealing with feelings. In life I think we're more so directed to brush feelings aside or ignore them, as opposed to practicing gaining a better sense of what they're trying to tell us. All feelings are telling. Do you have anyone in your life who'd be good or helpful when it comes to helping you gain a better sense of what exactly it is you could be feeling, given your current situation?
