Was the previous transaction one you created yourself?
Sadly both are not created by me, I am the owner of the address 1CtPpiYCVnQxgrJj5KtsjQP9KanXUx2CrN waiting for the second transaction (3dbc3b1bae55a4b801974e7f85ff17da8cdc1a41bd361b78a1ef2986897343c4) to be confirmed, which depends on the first one (73e2950f926f4cf982c62d504beb18127a294046a7ed2a80db88682ebf982c5f) to be confirmed !!
Well, you either have been scammed or got lucky because you didnt go first.
73e29 depends on 52f56[1] which depends on 5b222[2] which is invalid, because there is another transaction 49e81[3] spending the same coins that has 641 confirmations.

Thanks, so in short, there is no chance my transaction https://tradeblock.com/bitcoin/tx/3dbc3b1bae55a4b801974e7f85ff17da8cdc1a41bd361b78a1ef2986897343c4 is not going to be confirmed ans will stay in limbo ?
Yes, its now invalid, because it (indirectly) depends on an input that is invalid.
