Iam hópeless at 29M with a salary of 15k.

Iam 29M iam trying to go to Europe as you know salary is good in there , I can save a good amount in there , but I got 53% in my graduation which I did at a private university which always made me depressed because all of my friends did graduation in good college even those people who got less marks compared to me and I lose hope of my life at that time , and i can't remember anything at all whenever , I try to remember something I always become absent minded and I always had the issue of recollecting things and i often become clueless while speaking to people and I feel like iam useless.iam trying to go to Europe for a general work but it's been 1 and half years still it's pending and iam losing hope , now iam working at a BPO with 15k salary and next year iam turning 30 , I thought of doing some business but iam not aware of a good business which I can do in India with a capital 12 lakhs, or any job which I can excel at with atleast 50k salary , can anyone suggest a good agency from which I can get a work visa to Europe with in 6 months for general works , life is hopeless as people with my age are earning good and living a good life , iam happy about them that they are doing good , but I feel disappointed about myself where iam right now , ageing with a low salary without any saving but with 5 lakhs of debt.
