Update on this: I applied for a name change online; turns out it costs around £49 (~$77) to have all the legal stuff sorted out, and some proof of my new identity sent to me (so I can apply for passports, etc). Gonna put it off until my next paycheque...also gonna ask my other friends and probably my family for their opinion.
Your support has convinced me I should probably go ahead with it though
