Feel like starting from scratch after 4months gap.

I lost my job end of October. So cancelled OTF to save money. From December to March my focus was fully on finding a job. I got a job in March and the first thing I did was to join OTF again. I went to Thread50 on Saturday and Strength 50 yesterday. I did so bad yesterday. I could only lift the smaller weights. I wanted to go to 60mins class today but my body hurts so much I decided to rest today. I plan to continue and I know from experience that I will be back in shape soon. Just can't wait for that day. Just venting.
