Is moving to UK from USA worth it in my situation? Help pls.

[MissIntrigued]

Hi. Apologies in advance if this is long, but I need some serious advice, maybe from someone in similiar situation.

I am 25 years old, female, live in NY. I am not rich, and often struggle with money, but I make it work here in NY. I grew up here, my family is here, I have a car here, an apartment I pay rent on. It's hard for me, but I make it work.

I really wanted to try living in London for a year or two, see the world a bit. I have friends there, sort of , so I do know some people there. I might even be able to get myself a Tier 1 visa. But, I guess Im wondering....is it worth it?

I work in a field in which salaries dont tend to be too high (social services). I manage to make it work in NY, but Im afraid if I come to London, and am only able to find work in this same field, will I be sturggling? Will I be forced to live in some crap neighborhood? London seems so much more expensive than even New York! I am more than willing to try a new field, but with no experience outside of healthcare Im sure I wont find a really high salary starting out in a new field. I have a degree in psych from a great school in the US, so I am more than capable of learning a new trade.

I guess it's something I direly want to do, and in the same way I still am scared of such a big move. I think it's the money thing that scares me most, i worry about losing the little amount of comfort and stability I have here by moving there. Worried about finding work, I guess, even if I do get the visa.

Anyone else in a situation like, or close, to mine? It seems that so many of the people that apply to HSMP/Tier 1 are in jobs such as banking , finance, tech where they are guaranteed a high salary no matter where they go.

Anyway, any input would be appreciated.......
