I have been very depressed the last few days

So for the last month i have been off work due to anxiety because i was being verbally harassed at my job.
The doctor put me off and i had to change my phone number to stop the texts and i also closed down all my social media. I had given my phone number to a close friend and my father and my union rep but other then that i have basically kept to myself.

I have been spending this time encouraging others here on MFP to lose weight while i lose my own.
The friend i gave my number to, for some reason has decided to stop talking to me and avoid me and i am hoping someone could help me figure out why as i have asked her but she wont tell me. Its been upsetting me a lot.. leabing me unwilling to eat and under motivated to get out of bed.

So 7 days ago i was speaking to my friend, we were talking about how my dad was coming by in a couple weeks to visit and she offered to let me borrow her air mattress so i could let my dad have my bedroom. I told her that would be great and she said she would dig it out tomorrow and call me and let me know.

Tomorrow came, never heard from her but that was normal, i figured she forgot, was no big deal

Third day rolled around and by about 8:30 that night i called and no one answered so i left a voice mail asking how she was and then made a joke about how "heavy" air mattresses were and just wanted to make sure she wasn't injured.

Forth day came, she hadnt called but sometime by lunch i woke up, weighed in and hit a new goal in my weight loss, i was excited so i took a picture of the scale and sent it to her with the text "woohoo". She didnt respond but i figured she was probably working and had her data off and would respond later on her break.

that night i had an emergency. i called my father a couple of times but he is really awful at answering his cell cause he leaves it upstairs and watches tv downstairs and never hears it. i felt very upset and called her to see if she could talk and on the first ring the phone cut out, i thought the cell phone messed up but when i called back i realized she had ignored the call and then shut the cellphone off. I didn't call again

5th day came and passed

6th day rolled on by and by that night i texted and said i was worried cause its unlike her to let so many days pass by without saying anything and that i hoped she wasnt in a car accident or something

7th day still no response.

Today i called work to make sure she had been in, cause as i said, i was worried, and it turns out she was in today and yesterday so she was fine and not in a hospital somewhere, my boss said. Her and i used to talk constantly, go shopping together and hang out during all our breaks at work and everything, i dont understand what it was that i did and if someone could point it out to me, i would really appreciate it.. how do you go from saying i will call you tomorrow to never speaking to me again?

I dont wanna feel this way anymore
