im only 14 and I think I might have hiv but I dont know help please

ok when I was around 10 years old my mom and dad broke up and split …so after that me and my mom went and moved in with this gay guy that had hiv aids…also my mom started doing drugswith the guy that had hiv started doing drugs with her…we lived in that house for like 1 mounth and I was still skiny at that time so anyways my mom started getting pritty sick she would pass out on the couch and if she wasn’t sleeping she would be doing drugs are out sleeping with other guys … so I would be at the house playing computer games and the gay guy would be there too so he would start coming around me talking to me he didnt seem like he would rape me are anything but I knew he had aids…so every night when I would go to bed I was fine.. the only part I worry about is if he raped me … I think if he raped me wouldn’t I wake up and feel him up my ass?… but anyways I am 14 years old now still pritty skinny and its pritty hard for me to gain weight and I grow pritty slow and also im not living with my mom are the gay guy no more im living with my dad… so anyways also that happen like a long time ago so then again thats weird…so ya I grow slow its hard for me to gain weight and I like playing bball but somtimes when I play I just get week …also everyday I would have a lot of groubling in my belly and also every so often I would feel this white thing on my lungs and I try to cough it out and it always comes out and it looks whight and it smells like shiiit and it also looks like a small brain so tell me do I have aids im realy scared!
