Any advice for not feeling consistently drained? I always feel mentally exhausted
It sounds like you have quite a lot on your plate - being a full-time student means just that, yet you are also working part-time, so it sounds like it's quite overwhelming. And whilst I appreciate that of course work is perhaps a necessity to live and pay for your studies, you can't underestimate just how much you are doing.
I can see there are positives - such as your boyfriend who you describe as incredible. You also have a happy and healthy family. This sounds great and of course having a good, solid support network is really important for well-being in general. However, I am wondering whether you have much quality time with these people or indeed, quality time to yourself to recharge your batteries? After all, you cannot pour from an empty pot - you have to re-fill your pot in order to put your best self forward in life.
You say that once all of the distractions have gone, you begin to feel drained. Are the distractions always helpful ones, in terms of self-care? Whilst it could be said that studying and working may provide some enjoyment (although this is subjective! And perhaps this is not the case for you - in which case, this is something that could be explored), and of course your boyfriend and family/friends are something positive. But, what is it that you are needing in order to feel rejuvenated and less drained? For example, are your boundaries blurred somewhere? Are you unable to shut off from your studies or are you bringing work issues home with you in your head and not switching off? Or even with family and friends, perhaps you take on a lot? If this is the case, then perhaps you could look at strengthening your boundaries. This is something that many people do struggle with. If you would describe yourself as being a people pleaser, then perhaps you struggle to say no, agreeing to take on tasks in order to keep other people happy. But this can lead to a sacrifice of time (of which it already sounds like you are limited!) and also your identity of what you actually want or need, rather than what other people want and need. Whilst of course we help those we care for, or do our duties at work/Uni, we need a boundary in place to keep ourselves emotionally safe and balanced. At the moment it sounds like there isn't that balance somewhere, as you feel so drained.
I work as an integrative therapist, which means I am trained in several modalities, however my main approach is Humanistic. I believe that we all inherently know what is best for us, however this knowledge of our own selves can sometimes become clouded by the influence of our life experiences and also other people around us. We lose sight of how to best move forward for our own benefit. The counseling experience provides an environment that is a safe space, non-judgemental and I hold client's with unconditional positive regard. This experience of being heard without judgement or interruption of agenda, can sometimes be unique for some people. Being heard in this way allows for accurate reflection of our experiences, including our roles within them. Reflection leads to self-awareness. This will enable growth of you as a person - to find the right solutions for you, whether that be by putting in boundaries with other people, or modifying your own behaviors (these are just examples).
Perhaps in therapy, you could look at the root cause of what is behind this feeling of being drained in order to move forward in a way that enables you to live a happy and fulfilled life.
I hope this answer has provided something useful for you!
