Do I have a mental problem?

I think that you may have anxiety issues and possibly suffer from bi-polar disorder as you mention highs and lows. However I hate putting labels on people so my advice would be to go and talk to a professional. There are some simple things that you can do to help, like breathing tecniques and have a look at Mood Gym (google it) that may help you to break any negative thinking.

It is not normal for people to get this anrgy about stuff. Though it doesn't have to mean that there is something "wrong". It could be because of your age and other stuff that happened in your life. I recommend you to talk with your doctor about this and see if you can have a psychologist to help you controlling your anger. It doesn't sound like something absurd and unfixable. Its just the fact that you have to calm down a bit.

That's an anger management issue, not mental illness. You can study how to deal with frustration better. Some counseling will help.

i could recommend that your buddy seeks help from a Counsellor somewhat than a Psychiatrist or a Psychologist first . Even going to the wellbeing care expert and discussing it with them will help find out the place the difficulty began from and then if he needed to work out any of the different 2 Professions, He might desire to be referred for help . the difficulty had to initiate from someplace and that's dealt with then the want take care of it . i'm so sorry that he feels this type . wish it extremely is of a few help to you ] Take care Knell 22
