Whats the best way of making myself feel better? I feek so used and useless :(?

I just left my job, im really finding it hard 2 find a new one. I just moved out of my home, back to my mums and on top of that iv just been used by this guy i know, i know that im vunerable at the moment...so i feel like i would do anything to make myself feel better. And now it just feels like kno 1 wants me around. Im in a state of desperation!! Plz can someone just give me some words of wisdom?
