Basically yes, your melee and unarmed skills are not up to the task, and your strength, agility and endurance are a bad combination for close quarters fighting. Try sneaking and ending combat to get away from them.
I cannot recommend making your own character highly enough, the premade characters in Fallout 2 have terrible tag skills ie. barter and throwing. And even worse traits. Heavy handed, skilled, and sex appeal.
But only the experience of a first play through will tell you these things, the beauty of the game is that you can still 'finish it' with any character.
Edit. dammit took to long to respond.

*No, seriously, read Pers' walkthrough if you have any trouble.
