I came through severe depression, and an abusive relationship (yes men can be the subject of abuse too), I very nearly didn't make it out the other end, but I scraped along and saw a therapist for nigh on 3 years. 5 years later and I am now at the best place I have ever been, shaving my head along with it. After being at such a low, you will appreciate the positives even more, it will be a long run, and learning to love yourself after something so profoundly life altering is a life long process, but it gets better every day, Learning to appreciate the fact that you chose to live instead of give up, to smile and carry on will give you the strength to become yourself and that new you just so happens to be bald.
Sorry for the long winded post, but essentially what I'm saying is, through all this hurt, you are still learning who you are, and if there ever was a time to change your appearance like this, it's now, because you're in complete overhaul anyway. Good luck, happy to help any time.
