You have not said if you've talked with Cosades. If you choose to do so, like ST says, he gives you a decent amount of gold to get your career started. He also tells you who the Blade trainers are and where to find them. Go talk with those in Balmora. Each of them gives you stuff you can use immediately. If you don't join Cosades, at least follow Logorouge's advice.
If it were me, though, I would return to Seyda Neen posthaste because that seems to be a much easier area in which to grow your char's skills and start accumulating weapons and armor in keeping with your major/minor skills while you get used to the game. The merchant sells some useful spells and will buy and sell merchandise. Depending upon how diligently you search, you'll find useful items and can collect ingredients to either sell off for gold to buy eqpt or to use making potions for yourself. The people in Seyda Neen point you to a cave with some bandits - use it for practice and a source of some more cash. There's a bedroll you can use to soundly sleep or you can evict the bandits and sleep there instead. There's a quest you can pursue if you want, and you'll find another opportunity for loot falling into your lap if you let it
There's an article on UESP listing differences between Morrowind and the later TES games. Reading it may help ease the adjustment. Your comment about the fighting is one such thing. Unless you're trying to RP a contrarian character, you really want to use weapons that fit with your major/minor skills, ditto choice of armor, ditto your choice of spells to cast and learning alchemy. With a level 20 alchemy skill, you can read the first effect any ingredient (up to four effects) has. So you already have a leg up in that area because you can choose which stuff you want to eat and stick with those that only have positive or neutral side effects. You can eat those with negative effects to see what happens, of course. Eating ingredients is one way to very slowly increase alchemy skill.
