Starting again

Well I am back! its been a long few months. I graduated last year and did the race for life and with one thing and another I fell out of the habit of running and didnt run again until October. I didnt have to start again from W1R1 but managed a decent 20 minutes. I only managed a couple of weeks of this and then stopped. I havent been out since My poorly pooch was diagnosed with diabetes and cushings disease in the November and until we got him settled (its taken until now) he has been up every night every hour for a long wee and long drink coupled with the stress of a mounting (and nearly at £2k vet bill) its been a horrible, horrible 6 months and I am glad we are approaching a dim and distant light at the end of the tunnel. Its still a struggle when he gets up every hour as its tiring and stressful and so running took a back seat. All my energy just went on staying awake at work. I hope I can get back into this. I'm more nervous that when I started last year!!! Will my body remember anything? Will I have to start again? Has anyone had 6 months off and had to start again? Where should I start? All and any encouragement gratefully received. Gutted at having to start again but I am taking the positive in this. I might read my posts from last year to see how far I got as a bit of a boost......Its good to be back (again:))
