I'm 71 days back into recovery after a three-year dark and twisted relapse after having accumulated 2.5 years of sobriety before that. And so, on that level at least, I can really respect and relate to the frustration you must be feeling now that you are sober, but not happy.
My experience has shown me that with dedication, one will discover what others have so wisely stated in this thread. That is, that drugs are symptoms of a larger system of dysfunction that must be addressed before loving oneself becomes possible. And, of course, being lucid and drug-free is an absolute necessity in order to effectively address these issues. In 12-step recovery programs, you will often hear references to "character defects." These are the true underlying causes of our dissatisfaction with ourselves and our lives. I destroyed myself for many years by using drugs as an easy, escapist coping mechanism that, at the time, alleviated a lot of painful opinions I'd held of myself - without even realizing that they were problems.
Lots of things caused me to turn to substance abuse - fear, pride, jealousy, resentments against others and myself, insecurity, anger. Coming to terms with these deficits and addressing them directly has completely changed the very nature of my existence in this world. I'm freshly into dealing with these issues properly, and it takes time. I developed these harmful personality traits over man years, and 71 days is a woefully insufficient period of time to expect myself to have corrected them. There are alternatives to 12-step programs, but my experience has shown me that nothing else on this Earth can replace the feeling of being truly understood by those who have gone through similar or worse struggles, put in the footwork, and now lead more fulfilling lives than the vast majority of non-addicts I've ever met!
My suggestion is that you give yourself time. Recovery is an on-going and extremely difficult experience that few who haven't experienced that journey are capable of understanding. And this makes it extremely easy to drag yourself through the mud. Be aware that you may have some pervasive, underlying issues to deal with and that it will likely be a long trek. But give yourself credit for undertaking what most people find themselves unable to! I make it a point before bed each night to look myself in the mirror and reassure myself that I deserve to be sober; that I deserve to be happy! It's not as cheesy as it sounds - and unlike most self-help processes out there, I have discovered that this one actually works. Keep active and be as honest as you can with yourself and with others.
Most importantly, you're not at all alone. Never forget that. It is clear to me that you really want this. And that you, like myself, deserve it.
