I feel your pain! Early level grouping can be frustrating, at least in part because many players are learning to play the game and don't understand how to be effective with the character they have, much less how to play with others. Higher level characters who are developing an "alt" will pretty much breeze through to the high teens on their own with some casual 2-3 person partying to speed it up a bit.

Here are some thoughts:
1. Use the chat channels to find a group. e.g. "LFG to complete (quest name)".
2. Focus on killing mobs (solo) at or below your current level. Tackling mobs 2 levels higher is tricky and almost suicidal if they are 3 levels higher. (BTW, "mob" equal a "bad character", one to be killed. They are generically known as "mobs"). "Grinding" is another word to know...it means repetitively killing mobs in one area for the purpose of gaining xp. It's also related to "farming" which adds the component of looking for raw materials for selling or for your profession.
3. Faster leveling in the pre-level 30 levels will generally come from quest completions. The other mobs you have to kill along the way will add to your xp.
4. Love your rested xp! If you have rested xp, your experience is doubled until that is gone. Many players will develop 2 or 3 characters concurrently allowing for several days of rest as you rotate through each character's rested xp. This one is harder to follow if you have one main character and limited patience.
5. There will be certain elite level quests (e.g. Hogger, Van Cleef) that will require help to complete. Elites, BTW, have many more HP than normal mobs and are usually not soloable in the early game. Finding another player trying to complete the same quest is the easiest, most satisfying way to get the quest done. You may have to be bold enough to chat your way into a party invitation...or do the inviting yourself. Most higher TG members will be willing to help for the last bits as well. As frustrating as it may seem, you will actually learn more by trying to handle things at your own level than by having a lvl 60 show up to kill everything in sight with one blow.

Hang in there! We've all been through it!
