Avoidant behaviour - new here

[elusivesoul]

Hi everyone, I'm new here. I felt so low today that I decided to find a support forum, so here I am.
I'm 33 and I've suffered from chronic depression and anxiety on and off since childhood. My condition is generally managed well with medication (Sertraline).
I have also self medicated with codeine for a few years. And what makes it all even more complicated is that I now show symptoms of hypothyroidism, which make me incredibly fatigued and low amongst other things. (I'm currently in the process of getting my thyroid function tested).
I'm doing a Masters and I have had quite a few absences from university, because I can't face going in. I feel like a failure. I feel guilty, I feel like I'm lazy. I hate my avoidant behaviour, which makes me feel worse. I have some friends at uni, but I often feel left out, even when I'm not. I just don't have the energy to make polite small talk. I feel so ashamed and weak to struggle with attendance when so many people have far more serious problems, and my education is such an amazing opportunity.
I live in London, England with my husband and 2 children.

I am also going to school and have been having issues with not going due to depression/severe anxiety. Does your school have a counselor or nurse? You can call them and explain them your situation and they can talk to your instructors to make sure you have a locked in position in your classes. I did this yesterday, and to my relief everyone was very understanding. Also does your school have a retention officer? They can help you not get overwhelmed if you are behind on things and help you get extensions for homework.

Have you and your doc considered raising the dose of zoloft? If at 50mg go to 100mg as you sound a bit depressed. Alankay
