Sorry to hear what you're going through, and welcome to the community.
Since you did not provide many details about your situation, I will try to offer some basic advice.
I tried to get help from a counsellor but she was a shitty person to ignore me and my issues.
Glad you sought help, it's the right thing to do in the first place.
How many counsellors did you see? Maybe you just met a bad one.
I suggest you talk to your family and say you're not feeling confident with your counsellor and want to meet a new one.
I'm off the track from studying. I don't feel like studying anymore. I don't know what to do in life. I don't know if I'll be successful.
Worrying about your future may be normal but if it comes to a point where you feel so distressed as to contemplate suicide, then you should seek help (which you did, and again, that's good).
What you feel right now might just be a symptom of depression and/or anxiety, there are many things you could do.
Along with counselling I suggest you talk to a psychiatrist. A good doctor will listen to you, won't judge you, and may be able to help you with meds and/or additional counselling.
Many psychiatrists, along with prescribing meds, also offer counselling.
My parents are nice and they have high hopes from me but I don't think I'll be successful in life.
You have a supportive family. Great, it means you can talk to them and let them know how you feel. You'll work it out together.
Be honest with them and don't be ashamed - suffering is nothing to be ashamed of, and seeking help is not a sign of weakness. It means you're fighting a hard battle, that's all.
Many successful people have struggled or currently struggle with issues, and taking meds can be of great benefit, believe me (years of personal experience).
Don't blame yourself for feeling like this - sometimes, just like the bones in the body, people's minds need to be taken care of, and there are many ways to do it.
I feel like I should end it all and commit suicide instead!
It is commonly said that suicide is a permanent solution, and that's true. But it must be a choice, and one you must make with a sound mind. You don't get a second chance after that.
I can tell you're struggling and your distress is real. A good mental health professional will understand that. If you feel confident enough you can tell him about your suicidal thoughts.
As you probably know, this kind of thoughts are common when one is struggling with mental issues.
Don't act on impulse, don't kill yourself before you've tried other options.
Keep seeking help, and remember: the sooner you start taking care of yourself, the better the outcome will be.
If you feel like, keep us up to date. In the meantime, take care.
