Think of it this way: You have external kinesthetic information coming in all the time that you are pretty good at interpreting such as temperature, texture etc which allows you to identify the items you touch.

You ALSO have internal kinesthetic information that is available all the time that you are either unaware of or not adept at interpreting.

If you want to get the hang of this "feeling" caper start by learning to notice and identify your internal kinesthetics without trying to pars them or label them as feelings or emotions. Go for strict descriptives. If you find it hard to notice your physical sensations then practice practice practice is the key, and start with the external physical stuff that you have to acknowledge.

Start by getting a base line.

What can you physical sensations are you aware of right now? For example - I can feel the seat under my buttm the keyboard under my fingers, the floor under my feet, the fabric of my clothing, the air temperature is just a little cooler than my skin, my hair is touching my face, my galsses are on the bridge of my nose, my left cheekbone is itchy, my eyes are a little dry, my mouth is a little dry, I am a bit hungry (specifically my belly feels tense and empty), my neck is very sore on the left hand side, I have a headache (specifically across my forehead there is a sense of pressure from the inside out, behind my ears it feels like someone is poking in), I have a small knot of tension that feels like it is coming from inside my chest, just under my sternum, it is small and tight feeling, my hands are feeling restless, crampy and fidgety.

Get as much detail as you can, take as long as you need.

Then over time put yourself in lots of different situations with different stimuli and REALLY track the changes in these sensations. Start to build up REALLY good references so you can learn to recognises variations form base line quickly.

Start to track what variations from baseline typically occur in which scenarios. Note which ones normally occur together - eg sweaty palms, plus rapid heart, plus hot flushed face, plus breathless, or Heavy sensation in centre of body, sensation of being dragged down, clenched hands, tesne shoulders, squirming or restless guts....

Once you have identified some of these sensation bundles that occur fairly regularly in response to certain stimuli, you can maybe roughly categorise them - restless, fidgety, hot, tense, relaxed, heavy, flat, light, etc are the first level of identifying your sensations as feelings. (you has them!)

When you NAME or identify these sensation bundles under a commonly accepted or understood heading like "happy" you are just re-labelling or perhaps reinterpreting physical sensations as Emotions. It is a shorthand way to convey to someone you are talking to , all of the minutiae of physical input you may be experiencing, and asking them to extrapolate from their own understanding of the label, and recreate, or remember the same sort of physical sensations.

You can even ask for clarification about these things to learn what to call the sensations if you have no intuitive grasp. Ask a friend: Hey, so when you have sweaty palms, rapid heart rate, twisting sensation in gut what are you feeling?

This is when you learn about context: At the top of a roller-coaster it might be 'excitement', if you are in real danger it might be fear, if it is in a scenario not involving physical danger, but involving risk to your status it might be nervousness, or anxiety. Ask around, get a consensus on the more common ones and learn the language.

This is what most people pick up fairly intuitively through interactions, and you can see very young children learning the language, being taught by their families to differentiate between angry and scared, hungry and tired and so on.
