I have never had a problem with lonliness, I have a lot of online friends, so I am never alone really. Do you chat on facebook or chat rooms? What kind of hobbies do you have to meet new people? Do you go to a gym? Are there no friends at work? If you want friends you have to be a good friend too.

You really need to get into therapy, especially with a borderline personality diagnosis, that will not get better without therapy, meds will not help long term. Many people with BPD are misdiagnosed with Bi polar as pdocs are not fully aware of what is going on. Are you totally sure there are no support groups in your area? I thought there wasnt in my area, it took dregging through the local newspapers and newsletters to find a group within driving distance. There were none online. You may have to travel but in the long term it will be worth it. Are there no free therapy sessions available in your countries healthcare system? I am not familiar with Canada.

There are free online DBT and CBT courses. Some clinics offer more intense online programs. These can be very helpful, might be worth looking into.
