Don't fret, there is always a good reason why that door closed.
I.E-
I had a caregiver who used to take me to and from the bus whenever the family member that I was living with at the time would go out of town. This was because I was not living anywhere near public transportation. I made plans with them and slipped up in the process. They got so angry that they refused to work with me anymore. It was as if they went from being nice to nasty in the blink of an eye. They also humiliated me in public. For a while, I was angry, confused, and very hurt. I thought that they were better than that.
At the same time, it was all for the best. Not long after, I ended up finding my own place right on public transportation. I have not needed any providers or anything and I pretty much take care of myself. This was while I was pretty heart broken for a while because I thought they were a friend.
Coping:
1. The night of the let down- I beat myself up pretty bad by getting drunk and blaming myself. The provider was also acting pretty ugly and immature.
2. The next day, I did manage to call up a mentor and ask for their advice by explaining the entire situation. They responded by expressing to me that the provider had the problem and not me. I then said that I got drunk and that is when she told me, "Don't drink more, pray more whenever someone rejects you."
3. The next night, I stayed up and watched movies and cartoons all night. I was also thinking, "I never want to see that person again."
4. I got free counseling at school when I transferred to a major university and it helped.
