You're definitely not alone with those up and down, all over the place feelings. Are you in therapy at all? Talk therapy, or group therapy, can be really helpful for depression, but like medications, it takes time for it to work. How long have you been on your medications? Maybe you need an adjustment? A therapist can help you come up with some good grounding skills for when you're not feeling okay. Also, my pdoc really wants me to try to walk for 30 minutes 5 times a week -- exercise has been proven to be as good if not better for treating depression as medications.

In regards to your friends, perhaps you could get lunch as a group or just one on one? I know how hard it can be to see friends get together and feel like you don't fit in anymore. Perhaps meeting one on one would be good. Also, there's nothing wrong with making new friends (much easier said than done, I know!) Perhaps take a class or something to meet new people.

It does sound like you're doing the right thing with your ex. Just keep reminding yourself how awful he is and how much better and stronger you are without him.

Try to take care of yourself! I know it's hard, I also spend a lot of time sleeping. Feel free to come here and vent as much as you want!
