My fucked up life getting better

My life is getting better but whenever i get on my feet again i get kicked back down and get like heaps depressed and shit like i thought i was going ok i had a boyfriend whom i thought loved me then he randomly dumped me and he dont miss me at all and it turns out he only dated me for sex so he could get wit me, once he got dat he ditched me he's sucha loser i was so hurt by it i just wanted to go home and cry and i kinda did i didnt get out of the house till 6 days later apart from work and skool but i didnt want to eat,sleep or hang out or even talk to anyone and i mean anyone i dont know why but now i know dat no guy is worth getting dat upset about its useless and doesnt help neither does alchol or drugs it makes it worse cus u get hell misreable but i will survive sadly, i have been listening to my friends supporting me! and ive started to move on im hanging out wth them and i try not to think about him and i always think now dat its a gd thing he dumped you and dat im better and i have more guts and that i deserve sumone dat treats me right and just self motivating myself and my friends have been so supportive saying dat my x is a jerk and dat im so better off now i still get upset when i think bout wat happened considering he dumped me by text the text keeps going over ova in my head it plays and plays i think wat could i do differently, but ive got to learn to control those thoughts but so many things make me think of him like everything its so hard,
