It took an ex basically pushing me into it for me to finally go and see someone, and it's something I am remarkably grateful for, as it helped me unpick a bunch of misconceptions and bad habits I'd tied myself up in.
I'm not unusual in this. I've just been reading about a study which found that people take, on average, 10.5 years from the start of their problems to seek help in fixing them. That's years of unnecessary misery.
If you're not happy, for a prolonged period of time, and you can't seem to fix the issues yourself, then please do speak to someone. It might take a couple of tries to find a decent counsellor (I was lucky to get someone I clicked with on my first try), but it's worth it in the long run.
