Praise be to Allah.
If your situation is as you describe, then you are not obliged to go for Hajj, because you are not able to do it as defined in sharee’ah. Allah says (interpretation of the meaning):
“And Hajj (pilgrimage to Makkah) to the House (Ka‘bah) is a duty that mankind owes to Allah, those who can afford the expenses (for one’s conveyance, provision and residence)” [Aal ‘Imraan 3:97]
“So keep your duty to Allah and fear Him as much as you can” [al-Taghaabun 64:16]
“and [Allah] has not laid upon you in religion any hardship” [al-Hajj 22:78]
And Allah is the Source of strength.
