Alone in Gurgaon

It's been almost 2 years since I'm in Gurgaon,but I'm all alone, No friends, no colleagues nothing. I'm just all alone. Never had gf, tried every possible thing but didn't work. I've a crush in office but she ignores me Everytime. I feel like I'm going into depression. I've no one to whom I can share anything that's why I'm sharing here. I don't know what to do, I'm just going into shell. Please help
