I've become such a weak pansy what should i do?

In recent weeks i'm beginning to realize that i've become a total puss, i feel so weak now. I used to work out every night at 1 am pushing my body to the limit, i trained myself to enjoy pain and not just in the sense of working out, but by allowing my body to get used to doing things it didn't want to. i could push myself to do all kinds of things i should have been doing. From studying, to getting to know that cute girl who sat next to me in college, i just got used to risk and the concept of never truly being comfortable. i was always on edge. Of course at the time i was taking alot of hits in my life, family was very much estranged and many of my connections with friends were severed by wars with one another. I felt all powerful, it was me against the world, getting stronger every day, working at my job, going to school, and kicking ass (of course not literally). Everything i was proud of was because of my own accomplishments and that made me feel great. Then one day i had some really bad ribs and got food poisoning, i lost at least 15 pounds in 1 week, it was hell on earth and i was totally unable to work out for months and even when i did my iPhone's headphone jack broke so i couldn't listen to music. So i become lazy and stopped.

Well its been a year since then, and i feel as though i've totally declined from the point that i was at, i think i could have totally reached my peak, i could have had it all, but now i'm skinny again and my phone is still partly broken. I feel such a lack of enthusiasm now, i used to have such a large degree of enthusiasm for life now i'm such a "meh" kinda person. in fact i have the same routine everyday. Before it was me against the world and i was winning becoming a stronger person with lots of positive energy and stamina to get whatever that needed to get done, done now i just feel like a panzy just clawing my way through the worlds infinite pimp slaps. My favorite thing to do these days is drink tea and watch the golden girls, and i'm not joking. What should i do? (FYI i mostly just worked out to get girls)
