As of maybe 3 years ago, could be longer, but I just seem to have lost the ability to lift properly, consistently and regularly. I haven't completed a workout in years. About half to 3-quarters through I'm panting, dizzy and feeling absolutely sick to the stomach. I try to sit it out, but normally I just end up wrapping up and driving home. The drive home feels like I'm half-cut and then it takes me maybe 2 hours when I get home to start feeling normal again. I almost dread going to the gym and struggle to drag myself, never look forward to it like I used to. I've had a few extended periods out the gym in the hope the break would do me good (as long as six months out, more than once), but it hasn't worked. I tried signing up for comps to try and inspire me and I just never quite got where I wanted to be and pulled out before they took place. Some possible factors: -poor diet (I comfort eat a lot of junk) -poor sleeping habits/long-term sleep deprived -stress (from work mostly, though it's eased off the last few weeks) -poor lifestyle choices (all tie in with above really, but raving, meeting birds, late nights, all that goes with it) -mild depression maybe (not diagnosed (I won't go) but all the symptoms are there) ^ even so, these are thing I've done all my life and never posed an issue before. Any advice? I could just quit the gym, but it has been the only constant in my life for coming up to 20 years now, and I wan the health and aesthetic benefits of going to the gym.
