Good on getting out there any way. I'll second the "A" for that. I think part of why I backpack is because every time it pushes my limits in new ways, and sometimes breaks me a bit. "Normal" life can get very comfortable, and that dead routine is, to me, a bit dangerous. Something that really shakes up your routine and state of normalcy is good once in a while (As long as it doesn't go sailing past Type 2 Fun!). I find backpacking to compress all the full range of emotions of life down, sometimes to within only a couple minutes (From deepest despair and misery to IT GOES!!!!!!11, or the fire sparks to life and you know your mild hypothermia will come to and end soon). Backpacking will make you stronger, and tell you a lot about yourself (Some of it you didn't want to hear but need to). Keep it up, and you'll see some really beautiful things.
Hope you are able to find more hiking partners. Still working on that myself. Well, I have some, but need more for the types of trips I'd really like to do (off trail is the best).
