OP I support your actions and hope you enjoy it there. Life is going to very very different in ways we don't imagine. You'll quickly find the differences... for example, the bathroom is different and not just from a 'sit or squat' perspecitive (I nearly threw up the first time I stepped in one; if you can, try to go at night when the heat doesn't make the stink 100x worse). You'll also find that most of your meals will consist of bread and beans; although they'll bring out the meat for guests, it really comes down to bread and beans; occasionally you'll get some veggies in there, but its more of a token appearance rather than something you can really chow down.
I actually wasn't in Somalia; I was in Sudan - but in Sudan they talked about how bad Somalia was (which took me by surprise). While Somalia is different for sure, I wouldn't be surprised if there were a lot of similar experiences~
Anyways I wouldn't put much trust in everyone with such strong polarized opinions; things over there are blown out of proportion.
It can be very very bad (especially politically), and many people over there know its bad (they just don't talk about it out loud), and it will probably hurt you very much the first time you see a lot of sad things, but the way people try to help eachother is just incredible...honestly I felt more welcomed there by the people than I would in any random city in the USA (Again not sure how Somalia will be).
Oh and just FYI: the whole "women have zero rights and are just beaten day in and day out" is overblown. For sure the man ultimately has power and I would have loved to see more gender equality, but its not as extreme as certain individuals here have written it [you'll find within the family - and by family you include not just the nuclear family, but all the cousins (Which can be HUGE because of the large number of siblings they have) on both sides - there is a lot more gender equality where the women can challenge the man a lot, although the final authority/choice does rest with the man. And if they want to argue and yell day and night about how I'm wrong day and night...I've been there, they haven't.
Stay safe though and take all the advice of people who have been working there and have experience - don't try to draw attention (although honestly that won't be hard. In Sudan I stuck out like a sore thumb and people literally stared at me 24/7 everywhere...and I'm not a female; however, surprisingly, you might have a slight advantage in that sense if you wear a hijab because then it will be EXTREMELY inappropriate to stare at a female...with a guy, no one cares) to yourself at all. Basic precautions can make a HUGE difference, but remember that sometimes it won't help at all (I nearly had my camera permanently confiscated by some army assholes).
