re: At what point do you go and see a therapist/ Do they really help?

Don't approach it like it's something only for people going through big things. If you think you should see a therapist, start looking for one.

Try and get out of your box if you can and change some things up, make an effort to meet like minded people and expand your social structure. We all go through ruts, don't think you don't deserve some help just because you are you. You owe it to yourself to be happy.

Good luck.
