Please help!

Hi guys.

So recently a lot of amazing changes have happened in my life and they are all things which would make anyone joyous and excited.

Unfortunately my mental health is making it so that these are some of the hardest times of my life. And I don't know what to do.

Last night these mental health issues ruined my relationship and my partner of 3 years has decided that I need time alone to heal and so had left me.

I feel like I have nothing left and mental health is ruining all of the best things in my life. I don't know what to do.
