im a 19 year old male. basicly my problem is this. i get periods where i really low and feel like i cont do anything and just want to lazy about doing nothing as i feel like i have no enegry at all. plus i dont sleep well i also made 2 attempts in commiting suicide but both failed and also cut my self. last week my college tutor seen cuts on my arm and he wants me to see my doctor cause he thinks i suffer from depression but i think it aint just depression. as sometimes i can be mega

Do you think that this sound like bipolar. if not any idea what it might be.
I have not told my family or doctor how i feel. and i dont want to go to doctors cause i scared she will think im crazy or something like that and dump me on some kinda crazy drugs.
thanks for helping.
