Aita for wanting to talk to my friend when I'm having a break down

For contacts I'm a 14 year old girl and this friend is 17,and she's going through something right now,but when I asked her to help me with my problem,she said that I shouldn't bring my problems to her because she's gonna through stuff,and I completely understand that,but at the time when I asked I was having a break down,and I was really stressed(Idk if I should say this but I'm also very suicidal and when I get stressed I tent to harm myself)but I'm just trying to figure out if I'm the a-hole?
