Welcome to HealingWell and the Depression Forum.
I am so sorry you are feeling sad but I am wondering if you have every been to a physician to find out if you have depression. If not that may be a wise step for you as there are many different treatment modalities available and perhaps one will work for you. Also is their a counselor or therapist at your school?
Support groups are a place for people to give and receive both emotional and practical support as well as to exchange information. People with health conditions, as well as their friends and families find support groups to be a valuable resource and get confirmation that their feelings are "normal", educate others, or just let off steam. IMHO joining a support group is joining a family.
Welcome to the HealingWell Family and I hope we can meet your needs. Stick with us.
You are not the only one who has cancelled therapy or Pdoc appointments. I have just freaked at going more then once and just cancelled and one time I even had to pay $50.00 for not cancelling 24 hours in advance.
No beating yourself up, remember it is babysteps. One tiny step in front of the other. You will make it through. No one is left behind.
I wish you peace.Kitt
