i struggle with this one too. i found it very hard to express this in words. but i found a poem that nailed it;

To sit on rocks, to muse o'er flood and fell,
To slowly trace the forest's shady scene,
Where things that own not man's dominion dwell,
And mortal foot hath ne'er or rarely been;
To climb the trackless mountain all unseen,
With the wild flock that never needs a fold;
Alone o'er steeps and foaming falls to lean;
This is not solitude, 'tis but to hold
Converse with Nature's charms, and view her stores unrolled.

But midst the crowd, the hurry, the shock of men,
To hear, to see, to feel and to possess,
And roam alone, the world's tired denizen,
With none who bless us, none whom we can bless;
Minions of splendour shrinking from distress!
None that, with kindred consciousness endued,
If we were not, would seem to smile the less
Of all the flattered, followed, sought and sued;
This is to be alone; this, this is solitude!

lord Byron

for years i threw myself into work, but that's a short term fix. i make an effort to reach out to people whom might have similar interest. it doesn't always work but nothing ventured nothing gained.
i also am pursuing more artsy things and learning new things
