The first thing is to find a counselor who will help diagnose if it's true depression. If it is, there are many medications which can help; my doctor and counselor both recommended one which does not have the side effects of the 'selective seratonin reuptake inhibitors' - believe it or not, one common side effect is gynecomastia and reduction of sexual function. Not something that I'd consider acceptable.
A psychologist probably cannot prescribe an anti-depressant, but he or she can contact your regular physician to write a prescription. You have to be open and honest with a counselor - and I can tell you honestly that it's difficult at first to trust someone that completely. No Freudian 'lie on the couch, why do you hate your mother' stuff. A good counselor will not tell you how you feel; he or she will help you find out how you feel - which is a huge difference. When you get a prescription, be very diligent, and know that it can take a week or two for the effects to be noticeable, during which time the psychologist or psychiatrist will want to see you to judge how the dose is doing. A prescription can be a short-term thing or a long-term thing; it turns out I've suffered low-intensity periodic depression my whole life, so the anti-depressant is now a part of my regular permanent cycle of medicines. For someone younger or who has only a single event, they might take you off the meds after a short time.
Depression is insidious. It sneaks up on you. In men, the first symptoms are usually not crying, tears, excessive sadness - men frequently display unexplained anger. I got to a point that I laid in bed for two days not eating, barely sleeping, crying, and wanting only for the pain to end - which is far closer to the edge than I ever care to go again. How close? I don't know, nor do I want to know. But with counseling and the meds, I'm happy again - and so is my family (mostly. wife still dislikes my boobs and disputes my need for support).
Maybe it's just me because I'm older and my priorities have changed a lot from my earlier years, but some things - like my general body shape and gynecomastia and ED and hormones that defy doctors' explanation and are giving me a more feminine body shape - just don't matter like I used to think they did.
Find a counselor. If you can't afford one, find a pastor or go to a community health clinic or something to talk to someone trained. Most clergy learn counseling in seminary, in case you didn't know. If you go to a doc and aren't comfortable, go to a different doc. You HAVE to be comfortable with a counselor - some of the discussions will be very personal and a little uncomfortable if you don't trust the counselor. (My first counselor, on hitting discussions of sex life with wife and gynecomastia and mixed feelings about that, bluntly asked me if I might be gay or trans - which led to a very interesting discussion that was quite valuable for me to have. If I hadn't trusted him, that conversation wouldn't have happened.)
Ask any questions you want, and I'll try to answer them. If you aren't comfortable asking on the forums, let me know and I'll get you my e-mail so we can discuss in private. Just please stay open to talking with people and let people care about you.
