It's very difficult to turn the table around in your case. Typically, if you were residing in the US from or before Jun 25 2015 but made short trips later, you could at least justify that you still maintained continuous residence by providing evidences of continuous residence, but your problem is that you weren't even physically present in the US and in fact were in Nepal when US designated Nepal as TPS country and that you came to US In July of 2015. Based on the CPP and CR requirement, you aren't even eligible for TPS.
You can definitely seek assistance from a lawyer but it's highly unlikely you will be granted the TPS status.
