STOPPED LIFTING FOR 2 MONTHS AND FELT LIKE DYING

Guys... I just started lifting again today after a 2 month break (previously id been weight lifting for ab 5-ish months. So im still fairly new, but for personal reasons i wasn't able to lift at all over the summer) and it was AWFUL my arms felt like spaghetti noodles, I went down from 85lbs on bench to 65lbs on bench, and after my arms were wore out i could barely do dumbell exercises with 10lbs like my arms were GONE. Like i felt worse than i did when i first started lifting. Well, on a positive note, when i first started lifting i Couldn't even lift the 45lb bar and had to start with a 20lb bar on bench w/o weights... so atleast i haven't regressed that much on weight, but as for stamina .... well.... thats a different story >_<
