Starting again...3 years later

Hello everyone! This may be a long post for those that feel like reading. If you don't feel like reading it, still feel free just to say hi!

3 years ago I started on this site. I was working at a restaurant, I was 21,and married. I lasted about a month and quit it all. Fast forward to last year March. I decided I was going to run. My dad runs, he is 50. About 8 years ago he was diagnosed with diabetes. He was pretty overweight and pretty bad off...he decided something had to change. He started running and lost a good bit of weight. He isn't far from what his weight is suppose to be. Anyway I decided to run with him. I had exercised at all in those year in between. I expected to be able to only do a mile. That was my goal. Once I got there I felt great and ended up running 3! I was so proud. I only ran about 4 more times after that 3 miles, faster every time. I started myself too far too fast and something was very wrong with my knee. It was swollen for about a month and hurt very badly. I saw a doctor is our area...he was quite rude and said all I needed was insoles that he conveniently sold. So I bought them...they didn't help and I quit running.

Now about a month ago a guy I work with (no longer in the restaurant business...I actually work for the Geek Squad at Best Buy) said he was doing a challenge on the Nike app if I was interested. 1000 miles in a year. Realistically I know I can't do it, but I figured it was a great time to start running and again and finally get into shape. I'm 6'1 and last time I went to the doc about 2 months ago I was 240 lbs. The challenge starts on March 1st, which is my birthday. I went with my dad and got a nice pair of running shoes for my birthday (Nike free 3.0 V5). I ran for the first time today...im a bit down about it because I had to stop at .71 of a mile. I couldn't even do a full mile. My foot was cramping up very badly and I stopped.

I am trying to be realistic this time around. I started back up here to try to fix my eating habits and iv started to run. Im not sure what my end goal is at this point. I know the BMI says I should weigh 180. Id love to be there...but I would be happy at 200. Im not sure if this combo of eating right and running will get me there, or if its not quite enough. I am going to give it my all though, and I hope to find some friends here, maybe in the same boat, or maybe they have over come this already. I am trying to take it one step at a time. I always had bad asthma my whole life, and because of that building up my lung capacity will not be fun...but I know it will be worth it.

If you took the time to ready all this, id love your thoughts, or advise! I look forward to hearing from you.
