Unfinished first poem

I enjoy writing but this is my first dabble into poetry. Haven't necessarily finished but wanted feedback. Written over a few weeks.

At some point I find myself floating through space 
How did I get here?
Only the interstellar serenity responds
The black hole threatens my equanimity

I strain to pull away from darkness,
suffocating under the weight of myself
Brilliant luminescence catches my eye  
Focus on this, focus on the light.

My heart continues to shatter, repair, repeat
The silence of my chaotic mind is deafening
Listlessly searching for a shooting star,
for myself... but also for others.

In this world, among these people,
I’m grasping to survive. 
When did the beauty of solitude
become the stigma of insanity?  

Floating, searching for a tendril of hope
for humanity, for earth, for myself
Too often I'm left with no words
When has my silence become my curse?

I'm trapped in this space, drowning under the expanse 
Unable to decipher the tides of my feelings 
I continue to numb myself 
Overwhelmed and incapable of being anything but a stranger
