Good friends or not?

Update : About a year ago my best friend mom died. I was very supportive. Now 3 months ago my mom was diagnosed with terminal cancer. At first my best friend was very supportive of me. Latley my depression has got the best of me because I lost my job. So we went out to lunch and I was super sad that day and being negative. Some times my depression can bring people down. Although if I am bringing someone down they should tell me but instead she ignored my phone and text message and blocked me on FB. I also told her I would see several doctors untill I get my anti anxiety medicine dosage I want. I really was not serious but that day she could tell I took the clonazapam. I think this is what bothered her the most. She text me about a week later and said she owes me an explanation for what was really bothering her that day. After she blocked me on facebook I called her from a phone number she did not recognize and I asked her why she did it. She lied and said she just deleted her entire fb

Update 2: What bothers me more is that she must not have thought of us as good friends to begin with. She has a friend that live about 4 hours away. Her friend smokes pot every day and has an abussive boyfriend. My friend cared enough to try to do an intervention on her friend and was willing to drive 4 hours to do it and never blocked her on Facebook.

Will I regret telling her to put me back on Facebook and go back to being friends like we were if she still needs space. I can control my depression.
