Also since few months, I am feeling that any social interaction, leaves certain lingering thoughts in the mind. So, I made my social interaction very less.
Earlier I used to thought that maybe it's due to meditation but now I think I have been facing this situation since childhood due to my personality. And this gap becoming bigger as I am growing older.
I also felt that sometimes we socialize just to escape from our minds. But still, I find overall at a loss.
I feel much of what you write about raushan. In my experience there is significant truth in what you write as well, but given that this awareness is stinging you in some way, one can infer (also relating from personal experience) that there is awareness, but not as much equanimity and compassion.
Yes, almost all our interactions socially potentially leave some trail in our psyche as well as the other person's. Foundationally all of us are suffering and being unskilled in our conduct, we do tend to act so as to ignite something in the other person. But I have found that the answer lies within us. As we see more clearly how at some level everyone is suffering (by watching the nature of our own desires and aversions and ultimately our own suffering), a natural outcome is development of deeper compassion for ourselves and then towards others. (these days I feel that this organic compassion is not towards some person, but towards all the suffering in general, within and without). I found my last retreat much helpful in developing this compassion more deeply, and organically by watching how I am suffering and miserable within.
There are 2 aspects to social interaction : volume of these interactions, and our skill in these.
A short term solution as you are implementing currently is to limit the volume. But as Dharma Bum pointed out, there is a minimum need in all of us for these social interaction to function in a healthy way.
So over time the long term solution lies in developing equanimity and compassion within, so that the lingering thoughts that are remnants of interactions between 2 or more suffering individuals, dampen and cause less (or un-observable) suffering.
It might be a cliche to preach about equanimity and compassion, but that is the best medicine I have practically found. As the foundational truth of dukkha becomes clearer, this tend to develop more naturally as we do not see ourselves and others, but suffering within everyone towards which we direct our compassion.
Even if you cut out social interactions, there is enough suffering within ourselves, to give our being a nice spanking every once in a while. If we socialize to escape our minds, cutting out social interaction can be also seen as escaping into our mind to cut out social interactions. Try to observe this more often, and direct compassion towards this innate nature of suffering that has all of us entangled. Imagine the individual as an apple on a tree connected through the branches and stems of suffering with all the other apples. Compassion as you see this will become directed towards the tree, rather than any apple.
Similarly the lingering thoughts are but the part of this whole tree like entangled state of our being rather than some communication specifically.
You might also benefit from a little retreat time if that seems doable...
