Thanks for your post, I had also been through some serious mental problem when I was in college.
I remember the suffering it causes me, and I even can't able to sleep because of the pain and overthink.
For those who are fighting with their mind I urge them to go and get some therapy , do some exercise intense, Do meditation .
I had taken medicine for 1 month. and also left some bad habits that are damaging my nerves and cells.
Always stay close to those who makes you happy is the also a therapy that will make miracle.
Go travel don't take tension
Just remember this phrase "This too shall pass" and be happpy.
