Im not depressed but thoughts of suicide?

im not unhappy all the time. i dont think about it all the time but when i do it constintly i dont have many friends and i think i might be doing this to be noticed but im not sure. I had some pills to suicide but i never was going to do it , i searched it on the net what the pill overdose wouuld do and it wasnt nearly enough, so i took it, after that i was about to take a paracedimal overdose but after seeign what it would do i oput it straight away, Im 13. in nmy option cl im really shy beccause i dont know one and dread going and usally wag. Im really confident and loud in ym homeroom though because i know all them. I would never comit susice but i always always think about it when i feel upset please is there anything wrong???
