Open Question: Could this be ADHD or something else?

I know it's summer but I'm horrified to go back to school because my school hate me because of my 'behavioural problems' and my lack of organisation. I apparently have the 'attention span of a goldfish' and I always start doing one things and ten seconds later I'm trying to sort something else out and have no idea what I was supposed to be doing. My family are getting annoyed because I 'act like a five year old' and am always running around. I can't sit theough long presentations or movies because I get distracted and am often told by people to sit still. Also, I'm scared to wake up every day in case I do or say something stupid and I keep thinking about suicide. The thing is, I'm scared because I know I'll be really happy in a few days/weeks and people will start getting freaked out (again). I really think something is wrong with me. My school think it's ADHD, my friends think it's bipolar disorder.

Open Question: Can I go swimming with my period WITHOUT using a tampon?

This week my camp is having a pool party, and I really wanna go swimming. I'm scared of using a tampon, and I've always used pads/pantiliners. My swimwear is a dark blue color, and I'm wondering if I'll be okay just wearing that in the water.I've been reading a bunch of mixed answers saying that you shouldn't, or it's fine not to use a tampon, but can anyone give me one definite answer?

Open Question: HELP!!! Swollen lymph nodes around collar bone ane neck!?

Hi im 16 and ive had a bunch of large swollen lymph nodes around my collar bone and lower neck for the past 3 to 4 months. im not sick, in fact i almost never get sickm even a common cold. i have a really strong immune system which makes this even more odd. the nodes can move around when i touch them but theres like a cluster of them and they are super easy to feel even just by touching my neck. i keep feeling them to see if theyre still there. and they are. my mom told me if i stop touching them theyll go away but i have a feeling this is more serious than that. by the way i am very underweight and i was anemic when i was like 7 but it only lasted a year (i took some vitamins) so i dont know if that has something to do with it. they dont really bother me unless i apply pressure, yet i always try to sleep on the side of my body with the swollen lymph nodes cause the pillow feels really nice and it somehow relieves the tight feeling. i dont want to see a doctor because i am soo unbelievably scared theyll give me a shot in my neck, or suck out some of the lymph node for testing or even worse cut my neck open just for a stupid sample.. i wouldnt mind if they just did an xray or something and then gave me antibiotics but the idea of haveing a needle in my NECK disturbs me and doctors always overreact to otherwise simply treated things to make money... omg now my neck hurts just thinking about needles. ahhhhh please help me, and tell me your experiences or what i should do or tell the doctor so they dont stick me with needles thank you.
